1: Classification of CD-R/RW discs. Currently, there are three main types of CD-R/RW discs on the market: green disc, gold disc and blue disc. These discs are classified according to the dye composition used in them. Named by the color. Among them, green disk has the highest market share. 1. Green disk: This is promoted and produced by companies such as TDK and MITSUBISHI (Mitsubishi). Because it has a price advantage over the other two disks, it is very common in the market. The colors of green disks include emerald, dark blue and other colors, which are different colors combined with the gold reflective layer. The organic dye used to make green disks is called Cyanine, which is very afraid of strong light. When making disks, an appropriate amount of titanium metal needs to be added to reduce the impact on it. Light sensitivity. Many companies recommend using green disks, not only because of its wide market coverage, but also because this material can accept a wider laser reading range and has better compatibility. Currently, many optical disc burners use green disks for testing, which can be said to be the best price. A typical example of cheap and good quality. 2. Gold disc: Because the organic dye used to make the gold disc itself is almost transparent and light yellow, this CD-R/RW disc also shows a golden color, so it is called a gold disc. The main companies that manufacture gold plates are Kodak and Mitsui Toatsu. They believe that the organic dye used to make the gold disk has better light resistance and can extend the time of storing data (more than 100 years). It is recorded exactly the same way as a green disc. 3. Blue disk: The characteristics of the blue disk are similar to those of the gold disk. It also saves data for a longer time. Since the number of products is relatively small and not many people use it, I will not introduce it here. 2: Key points for purchasing CD-R/RW 1. Pay attention to the disc brand. CD-R/RW recording discs do not have high requirements on the manufacturing process, and many small manufacturers can produce them. This is why there are so many fake and inferior products on the market today. one. We must keep our eyes open when purchasing, and do not buy low-quality discs just for a few cents, because in the end we will only suffer. At present, most of the discs on the domestic market are Tsinghua Tongfang, BENQ, Leide and Maxell. Among them, BENQ's original discs are the most cost-effective. Of course, Leide and other brands are also very good. When purchasing, you should pay attention to whether it is a counterfeit, and carefully check the workmanship and surface printing quality of the disc. The best way is to compare with several others. You will be able to tell the difference between Li Kui and Li Gui at once. 2. Pay attention to the appearance of the disc. Although CD-R/RW recording discs are not as delicate as DVD recording discs, they are not as wear-resistant as pirated VCDs. Therefore, when we buy CD-R/RW discs, we must first observe the surface of the disc. Whether there are obvious scratches or hard damage, if the disc recording surface has obvious defects, such as impurities, bubbles, etc., it means that the hope of successful recording to the disc is very slim. Also note that there are impurities in the paint mark on the back of the disc and small scratches on the recording surface. Although they have no direct impact on the success of recording, both will greatly shorten the life of the disc, which goes against our use of light. Storage to achieve the original intention of long-term data preservation. 3. Pay attention to the quantity you buy. Some friends have just bought a recorder, which is very new and exciting. They always feel that there are a lot of things to burn, so they buy more than ten or twenty recording discs at once, waiting for burning at any time. Once the quality of the discs is not satisfactory, and the probability of flying discs is high, I want to change to another brand, but because I bought too many, I am reluctant to discard them all, so I have to slow down the recording speed. This not only increases the wear and tear of the recorder, but also brings a lot of hidden dangers to the security of the data you save. It is very likely that if you can read it this time, the disc will fail next time. Therefore, when buying discs, you might as well pick out a few brands and buy one each, and test it yourself to see which brand of discs your recorder is most compatible with. In this way, you can avoid paying unnecessary tuition fees, and you can better understand your own temperament in loving the machine. It can also shorten the running-in period between the machine and the disc, laying a good foundation for smooth recording in the future. Although there are dozens of brands of discs in the market, there are still only a few manufacturers with factories that actually produce them. We can see this from the disc information when burning. There are only a few major companies that provide disc dyes and master discs. factory. We can use this manufacturer information to determine the quality of the disc and whether it is a genuine recording disc. It should be noted that because Japan has dominance in the field of optical storage and has mastered many core technologies, most of the well-known brands among the manufacturers of recording disks are also Japanese.
1. Sun Uranium Electric 2. Mitsubishi Chemical Mitsubishi (Mitsubishi Chemical) is also an old Japanese recording disk manufacturer. It has strong R&D strength and complete product production lines in the field of optical storage media. Unlike Sun Uranium Electric, Mitsubishi's recording disks are the most popular in the country. The sales and publicity in the market are relatively comprehensive. Mitsubishi's recordable discs can be purchased in most electronic markets in China, and they have won a good reputation due to their outstanding quality. This can be seen from the fact that Mitsubishi Deep Blue music discs, which have been discontinued, are still purchased at high prices. see. Of course, good quality is also relatively expensive. 3. Maxwell is the same as the above two brands. Maxell is also an old Japanese recording disk manufacturer. The DVD recording discs of this brand are also of good quality and are relatively common in the market, but their promotion efforts do not seem to be as strong as Mitsubishi's. Of course, their domestic popularity is not as high as Mitsubishi's. 4. Ricoh Ricoh is one of the leading manufacturers in the core technology of DVD burners. It has the right to speak in this field. The compatibility of its discs is very good. This may be because the profit of DVD burning discs is too low. The company no longer produces its own DVD recording discs. Ricoh's discs are now manufactured by Ritek in Taiwan, China. Of course, the technology is still Ricoh's patented technology. 5. Ritek Ritek is a large optical disc manufacturer in Taiwan Province of China and the largest optical storage manufacturer in the world. In the CD-R era, Ritek worked as OEM for TDK, Fujifilm, Victor and other brands. With many years of experience in optical disc production, the quality and compatibility of Rite's DVD recording discs are now very close to Japanese products. The Japanese brands it manufactures include Ricoh and TDK. 6. CMC (Central) CMC (Central) is also a major optical disc manufacturer in Taiwan. Unlike Ride, CMC's products focus on the mid-to-low-end market, and the product prices are relatively low. In the domestic market, the main discs produced by Zhonghuan include Philips platinum, water blue, visual gold discs, and Audio discs. 7. Prodisc
