Introduction
The types of burning disks are:
1. From the perspective of whether it can be erased after burning, it can be divided into two categories: one-time burning disk (cd-r , Dvd+R, dvd-R, etc.) and rewritable recordable discs (cd-rw, DVD-rw, DVD+rw, etc.)
2. Divided into CD-R (700MB) from the perspective of capacity , DVD-R (4.7GB), DVD+R DL (8.4G), etc.
Working principle
The working principle of CD-R and DVD-R is to use laser to burn small pits (Pit) on the blank disc. Such unevenness represents The numbers "0" and "1" are added. In order to achieve this goal, a special dye must be applied to the disc. Burning discs all use organic dyes as the main material of the recording layer, and different dyes reflect different colors on the disc. There are mainly gold disks, green disks and blue disks in the market, and their data recording and reading principles are the same.
Burning principle
Physically, the single-layer burning mechanism of DVD+R DL discs is very similar to that of single-layer DVD+R discs. This is because the 55 microns between the two layers It is much larger than the focal point size of the laser beam or the distance between tracks. The center of the laser beam is focused on the track of the recordable disc. However, when the laser power is increased in a short period, the dyed recording material will absorb the laser power to change its chemical structure or color. These inscribed grooves form the corresponding pits of DVD-ROM (read-only disc). DVD players and DVD-ROM drives only detect these marks like the pits of read-only optical discs, but do not read the grooves of recordable discs.
The tracks of recordable discs are slightly unstable for a long time. The read head will also detect the instability of the track and control the rotation speed of the disc. The Wobble signal is modulated by some disc information and contains a location physical address information called ADIP (Preset Groove Address). ADIP information also includes whether the disc is single-layer or double-layer, and which layer is being read by the optical head.
Logically, DVD+R DL version 1.0 only defines the tracking method (OTP). The spiral track on the first layer is outward, but on the second layer it is opposite or inward. Burning will start from the data area 24 mm in diameter from the innermost circle of the first layer. When the burning process reaches the data area 58 mm in diameter from the outermost circle, it will jump to the second layer and continue burning from the outer circle. If the recording stops before 24mm from the innermost circle, the Lead-out area will be created during the end process.
Historical development
Green disk
The green disk is the earliest recorder developed and produced, and it uses the cyanine dye invented by the Japanese "Taiyo Yuden". Since the CD-R standard was based on cyanine dyes at the time, the compatibility of green discs was the best, and it could basically handle all burners. The cyanine dye is characterized by high sensitivity and can quickly form pits, but the problem that follows is that the green disc is too sensitive to strong light, and it is easy to scrap the disc if it is improperly stored. Some optical disc manufacturers have added materials that are not sensitive to light in the cyanine dye, and the color has also changed, which is our common golden-green disc.
Jinpan
In response to the shortcomings of cyanine dyes, Mitsui Corporation of Japan has developed phthalocyanine dyes. The material itself is light yellow, and it becomes golden yellow when mixed with the golden color of the reflective layer. This dye has strong stability and is not sensitive to strong light, but it has higher requirements for the writing frequency of the laser head. The storage time of gold disk is the longest, more than 100 years, suitable for storing some important data.
Blue Disc
This is a metalized AZO organic dye developed by Mitsubishi Chemical Media, and uses low-cost silver as the reflective layer. The Mitsubishi dark blue and vinyl discs that we usually see all use this dye. Its characteristic is that the data recording is relatively accurate, but the burning speed is limited, like Mitsubishi Deep Blue's nominal speed is only 16X. However, due to its excellent recording quality, it has been sought after by many enthusiasts. The storage time of blue discs is also very long, and the official claims have also reached 100 years. The green disk is characterized by good compatibility, the gold disk has the best stability and the longest storage time, while the blue disk has excellent recording quality and the same good shelf life. In fact, for ordinary consumers, it is not important which disk to choose, the key is to be able to cooperate with your recorder tacitly.
Type
1. From the perspective of whether it can be erased after burning, it can be divided into two types: one-time burning disc (cd-r, dvd+R, dvd-R, etc.) and erasable Write and record discs (cd-rw, DVD-rw, DVD+rw, etc.)
2. Divided into CD-R (700MB), DVD+R (4.7GB), DVD+R DL from the perspective of capacity (8.4G) etc.
3. From a functional point of view, the burning disc can be burned as a data disc (can be used to burn various data, such as document backup, program backup, etc.), CD music, VCD video, DVD Video, operating system CDs and various application system CDs, etc.
Quality identification
Pay attention to the disc brand
CD-R/RW discs do not require high manufacturing processes, and many small manufacturers can produce them. This is one of the reasons why fake and shoddy products are flying all over the market. We must keep our eyes open when buying, and don't buy those low-quality discs for the sake of a few cents, because we will only suffer in the end. At present, most of the discs on the domestic market are Tsinghua Purple Disc, Tsinghua Tongfang, BENQ, Lai De, Sony, Verbatim, Risheng and Maxell and other brands. It is to pay attention to whether it is a counterfeit product when buying, and carefully check the workmanship and surface printing quality of the CD. The best way is to go to a few more shops for comparison. Li Kui or Li Gui will be able to distinguish it all at once.
Pay attention to the appearance of the disc
Although CD-R/RW burning discs are not as squeamish as DVD burning discs, they are not as wear-resistant as pirated VCDs, so we bought CD-R /RW discs, you must first observe whether there are obvious scratches or hard injuries on the disc surface. If there are obvious defects on the recording surface of the disc, such as impurities, air bubbles, etc., it means that the hope of successful recording of the disc is very high. It's slim. It should also be noted that the impurities in the paint print on the back of the disc and the small scratches on the recording surface. Although they have no direct effect on the success of the recording, both of them will greatly shorten the life of the disc, which violates our use of light. Storage to achieve the original intention of long-term preservation of data.
Pay attention to the number of purchases
Some friends just bought a recorder. They are full of freshness and always feel that there are a lot of things to be burned, so they bought more than ten or twenty pieces at once. Burn the disc, waiting to be burned at any time. Once the quality of the disc is unsatisfactory, the probability of frisbee is high, and I want to change to another brand, but because I have bought too much, I am reluctant to eliminate them all, so I have to slow down the speed of burning. This not only exacerbates the wear and tear of the recorder, but also brings a lot of hidden dangers to the safety of the data saved. It is very likely that this time I can read it, and the disc will go on strike next time. Therefore, when buying a disc, you might as well choose a few brands and buy one each, and try it yourself to see if your recorder is most compatible with that brand of disc. In this way, you can not only avoid paying unnecessary tuition fees, but also better understand your own temperament of loving the machine, but also reduce the running-in period of the machine and the disc, and lay a good foundation for smooth recording in the future.
How to buy
1. Observe the front printing layer. The label layer of some existing burning discs is not coated with protective paint (or only a little). This kind of discs Due to the lack of a layer of lacquer protection, data preservation after burning cannot be guaranteed, and it is also prone to wear during burning, so it is not suitable for use; in addition, some burning discs have their label layer painted and printed twice. In the case of (or above), it is best not to use this type of recording disc, because it adds unnecessary weight to the recording disc, which will only bring harm to the burner and no benefit.
2. To observe the coating layer of the inner ring, we can first observe whether the paint on the innermost ring of the disc is uniform and forms a regular circle. The paint on the innermost circle of some burning discs is overflowing. These are generally rough-made products, so you need to be careful when buying them. In addition, if the paint on the edge of the innermost ring has formed a gray-black color, then such discs are generally not to be bought. Just because if the paint on the edge of the inner ring has formed a gray-black color, then the air and the paint on the disc have been in contact with each other and the disc has slowly deteriorated. At this time, the disc is generally used soon, and the data cannot be read on the optical drive.
3. Observe the overall coating layer This is to check whether there is any leakage on the overall coating layer when the recording disc is reflecting light. If the disc is found to be missing during observation, then the disc may be burned without problems, but when the optical drive reads the missing part of the disc, file corruption will occur Or the program cannot read it, so it is best not to buy such a burning disc.
4. Observe the outermost edge of the disc Here you can check whether the outermost edge of the burning disc is flat or not. If the outermost edge of the disc is flat, it means that when recording or reading data, the high-speed rotation of the disc will not cause chaos and shaking. Otherwise, it will easily cause the phenomenon of picking and damage the recorder or optical drive.
5. Observe the paint level of the disc, the quality of the burned disc depends on the paint level. When we want to observe the layer of paint on the disc, we can use the fluorescent lamp to illuminate it from the back of the disc in the highlight light to see the clues. Generally, the more layers, the more distinct the aperture is, the better the disc. In addition, the colors on the recording discs are not meaningless. Different color recording discs have different characteristics. For example, the aqua blue recording disc has a particularly distinct gradation aperture.
6. Choose different color discs WATER BLUE (lake blue) according to the purpose ---- use the latest anti-data loss technology to greatly reduce the Buffer Under Run situation, so in one-to-one and one-to-one It has super stability in the 1x-12x burning mode. The best burning format is: data (DATA)
OMEGA BLACK (black)-pure black material, can prevent light damage in the organic dyes, greatly extend the life of the CD-R, save Longer. The best burning format is: Games (GAMES, DATA, MP3, PS2)
PURPLE (purple) ---- can prevent the organic dyes in the light damage, greatly extend the life of the CD-R, save Longer. The best burning format is: games (GAMES, DATA, PS2)
APPLE GREEN (apple green)-the organic dyes in it are extremely sensitive to weak signals and can reveal the sound range of the recorded music Extensive, it can be said that it is specially designed for digital music. The best recording format is: song (DIGITAL AUDIO, MUSIC CD, DATA)
meteLATE RED (metallic red) ---- can make the laser light pass through completely,
COPPER MINE (mineral yellow)----can make the laser light pass through completely,
ORANGE (orange)----can make the laser light pass through completely, making the CD-R receive signal perfect. The best recording format is: music (MUSIC, CD, DATA, VCD)
DIAMOND (pure silver)-the color of the burning surface is the same as that of ordinary VCD, and the "string audio frequency" "Especially low, which can minimize the appearance of lines or mosaics when reading documents. The best burning format is: video files (VCD, MPEG, FILE)
burning format
Optical storage products are developing in the direction of rewritable and large capacity, while DVD The compact disc has a large capacity and is undoubtedly another ideal choice after CD-R and CD-RW. Because of this, foreign manufacturers are vigorously developing rewritable DVD technology. At present, DVD discs mainly have the following four mainstream recording formats.
DVD-R format
Data in the DVD-R format cannot be modified after being written, so it is also called a write-once DVD recording format. The burning principle of DVD-R discs is similar to that of CD-R. It uses lasers to write data on the dye layer for reading by DVD-ROM drives or playing in DVD-Video players. There are two formats of DVD-R: DVD-R(G) and DVD-R(A). The difference is that the wavelength of the laser is different when recording. DVD-R(G) uses a 650nm laser, while DVD-R(A) uses a 635nm laser. DVD-R(G) is mainly used for recording discontinuous archive files for home and office users, and adopts copy prevention technology. It is a unified standard formulated by the DVD Forum in 2000. DVD-R(A) was first proposed by Pioneer in 1998.
Format
DVD-RAM is a rewritable DVD developed by a group headed by Japan’s Hitachi, Panasonic, and Toshiba. It has received the DVD Forum (a definition and support for DVD format). The support of industry groups) is mainly divided into two types: dedicated for computers and dedicated for household appliances. Its burning principle is the same as that of CD-RW, and it also uses phase change technology. DVD-RAM burners are somewhat similar to MO drives. DVD-RAM discs have a clip-on protective case, so neither DVD-ROM drives nor DVD players on the market can read them. The biggest advantage of DVD-RAM discs is that they can be rewritten more than 100,000 times, ranking first among all rewritable recording media. The standard DVD-RAM disc developed in early 1998 has a capacity of only 2.6GB for a single layer and 5.2GB for a double layer. It was changed to single-layer 4.7GB after 1999, and the double-layer capacity was also changed to 9.4GB in 2000. However, DVD-RAM has many shortcomings. DVD-RAM discs are fragile and difficult to maintain data integrity, and cannot be used on DVD players or DVD-ROM drives.
DVD-RW format
The DVD-RW specification is led by Pioneer. The DVD Forum completed the 1.0 version of the specification in November 1999 and completed it in mid-2000 1. Version 1 specifications. DVD-RW products are positioned in consumer electronics products, mainly providing functions similar to the past VHS video tapes for consumers to record high-quality audio-visual multimedia data. However, the functions of DVD-RW have also been applied to the computer field. Apple and Compaq have used DVD-RW drives as mass storage devices. The advantage of DVD-RW is that it has good compatibility. It is the earliest repetitive recording medium that can be used to store video, audio and other data, and most DVD-ROM drives can read DVD-RW discs well. . The original DVD-RW burners could not burn CD-R and CD-RW discs, but there are DVD-RW drives that support these recording formats. The disadvantage is that the recording speed is slow.
DVD +RW format
The specification of DVD +RW is dominated by the DVD Alliance and is not an official specification of the DVD Forum. Microsoft has clearly stated that it will support it in the next-generation operating system. DVD+RW. DVD+RW products are also positioned in the fields of consumer electronics and computer storage products. DVD+RW is an extension of the DVD standard. Compared with other DVD recording formats, its compatibility is the highest among the existing recording formats. DVD+RW discs use phase-change materials, and its reflectivity is the same as that of double-layer read-only DVD discs. Therefore, DVD+RW eliminates the problem that DVD-ROM drives are difficult to read data. The DVD+RW drive has comprehensive functions and fast writing speed. It can read DVD-R/DVD-RW discs, but cannot burn DVD-RAM/DVD-RW discs. DVD+RW provides about 1000 rewriting times, which can help you complete video, audio and data storage. DVD+RW has a shortcoming, that is, it cannot record write-once DVD-R discs, but the DVD Alliance promises to release DVD+R, a write-once disc dedicated to DVD+RW burners. Relatively speaking, the current DVD-R/RW has the best overall performance. Pioneer, Sony, Mitsubishi, and TDK, the four major brands have a good reputation. After all, the first two are the makers of DVD burning standards, while Mitsubishi and TDK have always been the manufacturers of recording disks for many recorder manufacturers, but they feel that Sony fakes more.
Well-known brand
Sun Uranium
The first one I introduce to you is Taiya Yuden (Sun Uranium), which is an old Japanese recorder manufacturer. The discs produced by this factory are of excellent quality and have good compatibility. It is just because of the sales strategy and price that they do not have an agent to sell them in China, but some discs in the domestic market are produced by this factory. .
Mitsubishi Chemical
Mitsubishi (Mitsubishi Chemical) is also an old Japanese recorder manufacturer, with strong R&D capabilities and complete product production lines in the field of optical storage media, which is different from Sun Uranium , The sales and promotion of Mitsubishi's recording disks in the domestic market are relatively comprehensive. Mitsubishi's recording disks can be bought in most domestic electronic markets, and because of their superior quality, they have won little reputation.
Same as the above two brands, Maxell is also an old Japanese recorder manufacturer. The brand's DVD recording discs are of good quality and are more common in the market, but it seems that they are not as strong as Mitsubishi in terms of publicity. Of course, the domestic popularity is not as high as Mitsubishi.
Ricoh (RICOH)
Ricoh (RICOH) is one of the leading manufacturers of DVD burner core technology, has the right to speak in this field, and its disc compatibility is very good. It may be because the profit of DVD burning discs is too low. The company no longer produces DVD burning discs by itself. Ricoh's discs are manufactured by Ritek in Taiwan Province of China. Of course, the technology is still Ricoh's patented technology. .
Ritek
Ritek is a large optical disc manufacturer in Taiwan Province of China and the world's largest optical storage manufacturer. In the CD-R era, Rhenium has worked as an OEM for TDK, Fujifilm, Victor and other brands. With many years of experience in disc production, the quality and compatibility of Rhende DVD discs are very close to those of Japanese products. The Japanese brands it manufactures include Ricoh and TDK.
CMC (Central)
CMC (Central) is also a major manufacturer of optical discs in Taiwan Province. The difference from Rhenium is that CMC's products mainly target the low-end market, and the product prices are relatively low. In the domestic market, the discs produced by Zhonghuan mainly include Philips platinum discs, water blue discs, visual gold discs, and audio discs.
(Precise disc)
Prodisc (precise disc) is also a major optical disc manufacturer in Taiwan. Many CD-R discs on the market use dyes provided by Prodisc. Its own brands include Smartbuy and Mitsubishi 52x speed platinum discs.
Differences
Specifiers are different
Different addressing methods
(mainly due to structural differences)
p>DVD-R uses low frequency (140.6kHz) wobble time, and relies on the addressing information pits pre-engraved at the convex track when addressing. This kind of addressing method has poor signal recognition. When the multiple speed is high, addressing is not easy to obtain. Therefore, -R high-speed recording will be relatively difficult.
DVD+R uses high frequency (817.4kHz) wobble groove time. Addressing is achieved by phase modulation of the wobble groove at the pre-groove track. In this way, the signal resolution rate is better- R is better, and the manufacturing process of the master disk is easier than -R, which is in line with the easy high-speed recording and easy production and manufacturing mentioned by the +R alliance.
About wobble: The wobble or jitter of the guide track is called wobble.
3. The required master disk is different. (Generally there is no difference in dyestuffs)
4. The production process is different
After the DVD-R is formed, it needs to be pre-written with a special pre-writer (the -R wired Disk). DVD+R is not required.
DVD+RW is currently the easiest to use DVD burning standard with the best compatibility with existing formats, and it is also cheap. The DVD+RW standard was jointly developed by Ricoh, Phlips, Sony, Yamaha and other companies. These companies established an industrial organization of the DVD+RW Alliance. DVD+RW is the only rewritable format that is fully compatible with existing DVD players and DVD drives, that is, it is fully compatible with real-time video recording and random data storage in computer and entertainment applications. DVD+RW can not only be used as PC data storage, but also can directly burn video information in DVD video format, which is a major breakthrough in the DVD industry. With the development and popularization of DVD+RW, DVD+RW has become a rewritable DVD standard that closely combines DVD video and DVD burners on PCs.
Features of DVD+RW:
Single-sided capacity 4.7GB; double-sided capacity 9.4GB
The longest single-sided recording time is 4 hours of video; The surface is 8 hours
The laser wavelength is 650nm, the same as DVD video
Data density at constant linear velocity
CLV and CAV recording
UDF (Universal Disk Format) file system
Quick format
Sequential burning or random burning
Lossless link (Split burning Will not waste disk space)
Burn finished products, all physical parameters are in compliance with DVD-ROM specifications
DVD+RW has the ease of use of DVD-RAM optical drives, and improves DVD-RW drive compatibility. Although the formatting time of DVD+RW takes about an hour, it can be formatted in the background from halfway, so data can be burned in one minute. It is the fastest DVD burner in practical use. . At the same time, the DVD+R/RW standard is also the only DVD burning standard supported by Microsoft.
The DVD-RW standard was proposed by Pioneer (Pioneer) in 1998 and received strong support from the DVD Forum. Its members include Apple, Hitachi, NEC, Samsung, and Panasonic. The 1.1 version of the official standard was completed in mid-2000. DVD-RW products were originally positioned as consumer electronics products, mainly providing functions similar to VHS video tapes, which can record high-quality multimedia video information for consumers. However, with the development of technology, the functions of DVD-RW have gradually expanded to the computer field. DVD-RW burning principle is similar to ordinary CD-RW burning, but also adopts phase change reading and writing technology, which is also a fixed linear speed CLV burning method.
The advantage of DVD-RW is that it has good compatibility and can save data in DVD video format, so it can be played on a DVD player. However, one of its big disadvantages is that it takes an hour and a half to format. In addition, DVD-RW provides two recording modes: one is called video recording mode; the other is called DVD video mode. The former mode has richer functions, but it is not compatible with DVD players. Users need to choose between these two formats, which is not very convenient to use.
Use
What kind of home should be placed for the burning discs?
Some friends like to stack the burning discs that have just been bought, and then put them on a CD In the barrel, when you need to use the burning disc, you can take it out and use it; the discs that have been burned are also stacked together. When you need to use it, you can turn them out one by one and search slowly, and then stack them up after you use them. As everyone knows, this is very wrong. We know that burning discs are very delicate things, and the body is very thin, and it is easy to deform when stacked, and it is more prone to scratches when the discs collide with each other. In fact, as long as the burned disc is slightly damaged, it may not be able to be used normally. So, can this situation be avoided by using a CD case? Not necessarily. A good quality CD case can indeed play a very good protective role, but the price will be more expensive, which may not be suitable for ordinary users; some CD cases are cheaper to sell, a few dollars each, and the quality of their production may be very rough . If you use this kind of box to hold the burning disc, although the burning discs can be isolated without direct contact, due to the quality of the box itself, the inevitable friction may also affect the burning when the burning disc is pulled out and inserted. Disk causes relatively large damage. If users want to save some money and want to protect the recording disk, they may choose a more flexible plastic film that can hold the recording disk on both sides. The flexibility of the film is required to provide a relatively smooth space for the extraction and insertion of the burned disc, and to reduce the chance of scratching the disc. Placing the disc on both sides can well fix the position of the disc, and the probability of the disc slipping out is greatly reduced. In addition, buy a CD rack and put the film in it vertically. The author believes that using this method can better protect the disc itself than using a CD case, and the price of the film is also relatively cheap, usually a few cents to a dime, which is very worthwhile for ordinary users.
What kind of recording disc should be used for different burning?
Some friends use the same kind of recording disc no matter what type of file is burned. In fact, this is also wrong. Generally speaking, the several types of recording that we use the most are: music CD discs, system installation discs and general data file discs. Relatively speaking, music CDs have relatively high requirements for sound quality, and good sound quality cannot be separated from a good disc as the underlying support, and only good quality discs can provide stable playback effects, so try to use A better quality disc is more suitable. Friends who often reinstall the system know that when installing the system, because it takes a long time to read the CD, if the quality of the CD is poor, it will often not be read smoothly, which affects the installation of the system. Therefore, if you want to make a system installation disk, you must buy a good quality recording disk. For general data file disks, we can also divide several levels of importance. For very important and frequently used data, you should use a high-quality burning disk; for ordinary important data, you can use a good-quality ordinary burning disk. But no matter what type of burning, one thing should be noted: every certain period of time (for example, three months, six months), you should check whether the burning disk can be read smoothly, and update and replace in time. . Otherwise, once the information is lost, it will be very regrettable.
How many times the speed to use for burning
Generally speaking, the burning speed is determined by both the recorder and the burning disc, and the maximum burning speed is in turn with the highest burning speed of the two Is consistent with the lower value of. For example, if the maximum speed of the recorder is 52X and the recording disc is 32X, then the maximum recording speed should be 32X. Some friends have bought recorders and burning discs that support higher burning speeds. For example, they all support 52X. In order to save burning time, they all use 52x speed for burning. In fact, this approach is not appropriate. Because music CDs and system installation disks have relatively high quality and stability requirements, especially for system installation disks, if the data written in the front is wrong during burning, it is likely to cause problems with the entire disk and eventually make it impossible to use it for smoothness. Install the system locally. In the case of the same burning disc, the direction of burning quality improvement and burning speed improvement is exactly the opposite. That is to say, for high-quality burning types, higher burning speeds are often difficult to ensure that the burned discs can be burned. To meet the actual needs of users, and the relatively low burning speed can basically ensure that the data is written smoothly and coherently in the burning disc, thereby ensuring the quality of the burning. Generally speaking, it is more appropriate to burn music CDs or system installation disks at 8~12 times speed. For ordinary data discs, higher recording speeds are also feasible, because CD burners generally have automatic error correction functions, which automatically detect and correct write errors during high-speed recording to ensure smooth recording. But the author believes that it is not necessary to use 52X to burn, because we generally use ordinary quality burn discs to burn data discs. Burning at too high speed will sometimes cause burning failure, or it will not work normally after burning. Use. Generally speaking, 32X is sufficient for burning.
Is "overburning" worth it?
Some friends may know that as long as the appropriate burner and burning software are used, it is completely possible to "overburn" the burned disk. Like the production process of hard disks and CPUs, when manufacturers make blank recording disks, they often reserve a part of the extra space on the outer ring of the recording disk, which is not marked. In the normal recording state, this part of the space cannot be used. Some burning software can recognize it. In order to make full use of the burning disc, some users hope to "overburn" it to increase the burning capacity. Although the pen can bring more capacity because of "over-engraving", the increased value is not too large, usually 20~30MB, and it is very good to be able to reach 50MB. The consequence of this is that the performance of the disc burned in this way is not stable, and it is often unable to be read normally after a period of time. Even if it can be read, it will bring more extra workload to the optical drive, which is not worth the loss.
How to correctly label the burned disc
A common practice is to write information related to the disc with a grease pen on the burned disc to facilitate the management of the disc In fact, this approach is also wrong. When the optical drive reads the burned disc, the presence of ink will make the rotation speed of the burned disc fast and slow, which is very unstable, which will affect the normal reading and the normal life of the optical head and other components of the optical drive. In addition, over time, the ink will slowly penetrate into the disc. As mentioned earlier, once an optical disc is damaged, it is likely to be scrapped, and the infiltration of ink is a more serious form of damage. Therefore, in order to extend the life of the burning disc and the burner, it is best not to write anything on the burning disc. And there are many other ways to label a disc. For example, when a plastic film or plastic box is used to store the disc, a small label with the disc information can be added to the surface of the film.
Generally, burn disks are used to save important files and data. Therefore, only by using and saving them correctly can we better preserve our important information and bring greater convenience to work and study. .
Save
1. Sun protection. Burning discs are different from ordinary discs. Don't put it under strong light. This will affect its use, especially green discs and blue discs. Because of their poor light resistance, if exposed to the hot sun, it will cause dyes. Mutation leads to the scrapping of the disc.
2. Anti-scratch. Generally, users are very careful about the data side of the burned disk, so there is no need to say more. But everyone is not very concerned about the back side of the burned disc (the side where data is not burned). Originally, the paint on the back of the burned disc is painted very little. Sometimes some cheap bulk discs are not painted at all, so it is easy to get a little bit of paint. The rough surface is scratched. If the reflective layer is accidentally damaged from the reverse side of the burned disc, the burned disc will be declared scrapped.
3. Anti-sticking. For the convenience of searching, users often put some labels on the back of the burned disc. Doing so will cause uneven distribution of the center of gravity of the optical disc, which will cause a lot of vibration when rotating in the optical drive, especially the high speed of the optical drive, which is not good for both the optical disc and the optical drive. In fact, if you pay more attention, you will find that the discs produced by those big factories (such as BenQ) always try to use not much ink, and the ink distribution is also very uniform. This is also the reason.
