Picture 1
With the broadband Internet, DC, DV enters the usual people's home, the massive hard drive we believe is increasingly overwhelmed, and the price of CD-RW recorders that have been high in price reach the ultimate 52x speed after the burning speed, the price is a drop Drop, more manufacturers have launched the land price of 268 yuan in the 52-fold speed recorder, plus the price of low price CD-R / RW burning disc (hereinafter referred to as disc), using discs to become ordinary users, low cost The best way to store and back up data.
As the saying goes, good horses must also match the saddle, facing up to hundreds of discs in the market, what should we choose? How can I know if I bought the disc is really bad? This has become a challenge for ordinary users and purchases.
Of course, everyone can test the test software that identifies the disc information, such as Nero comes with CD Speed, INFOTOOL and CD MATE, can view the manufacturer of discs, etc. However, when you buy a disc in the market, you will not be able to go with your own love machine to go ^ _ ^, then have there any simple and intuitive way to identify the manufacturer of discs in the disc? The answer is yes. Although the brand of the discs are hundreds of hundreds of or even thousands, the thousands of variables are not from their Zong, the main disc production manufacturers are then twenty or thirty, and most of the disc production manufacturers of most of domestic sales are mainly It is produced by Taiwan manufacturers and their factory in the mainland and the mainland. Today, the author introduces a small method of identifying the manufacturer by looking at the copy of the disc.
First introduce what is the loop of the disc. Simply, the ring is in the inner circle of the disc, the word code outside the clamping area, because it is arranged around the clamping area, so it is used to the ring code, as shown in the figure is the largest in Taiwan. The circulatory map of the three discs manufacturers can see that each manufacturer is not the same, which provides a basis for the manufacturer of the fellow visual identification disc. The coding in the figure records the production date of the disc, the production line employed, and the type of dye used. Let's take a brief introduction to the circular code information of the market discussion of each disc production manufacturer, if there is no special instructions, X represents any English letters, Y represents any Arabic number:
Ritek.co (德): RXD (a) 74 (80) M-YYYYY 74 (80) DA, where x represented English alphabetical disc dye type, D represents data dedicated disc, A represents music dedicated disc, Only music dedicated dishes are common from the back DA letter:
RFD super high speed platinum RAD high-speed Platinum RJD medium speed platinum RSD low speed platinum RVD high-speed waterland red medium speed waterland RGD Vision Gold RKA music Fuel RAA music Fuel RTD greater than 700M large-capacity white gold disk RWD Repeatable write.
德德 is Taiwan's largest CD-R / RW and DVD burning disc production manufacturers, and the famous brand discs in the domestic market are produced with 德 自 有 有 有 品kets RITEK and RICOH, TDK. In addition, Jude's branch in China, such as Chongqing Xinhua only produced RFD ring, the platinum pan and the CDRLSS80M-YYYYY, the RFD disc and the disc vary of the discs of the Taéaa lies in no picture in the picture, common The first loop discs, such as Tsinghua Tongfang, such as Xinhua CD, not the above loop code, is definitely a fake.
CMC (Central): CD-R 80 XXLHxyyyyYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY, the famous brand discs in the domestic market have Philips Platinum, Waterland, Visual Gold Disc, Audio disc and MitSubishi technology and Mitsubishi series discs produced by dyes, MITSUBISHI discs have different CMCs, will be described later. Prodisc: R (W) 0YY-YYYY-YYYYY, R indicates a disposable write disc, and W represents repeatedly written discs, wherein R008, R020, R043, R046 in the first group, R049, R052, etc., the larger the number, the higher the burning speed you can achieve, and the famous brand discs in the domestic market have a self-brand SMARTBUY and MITSUBISHI52 times speed platinum disc.
Princo: Taiwan's old four, but the mainland market is not common, the ring code is: 79.50xx SHR-00YY.

In addition, the one-time write disc of Mitsubishi Ring Code is a blue plate using AZO dyes, and the codes of the silver disc of Mitsubishi can be used as a fine disc ring code. Wiltech: Hong Kong manufacturers, Sony specified by the OEM manufacturers in the mainland market, so Rongli's ring code has its own cyclode CD-R 80min WL21-YYY and SONY Ring Code U5-00YY, generally Wedding friends prefer to use Rongli disc.
Leaddata: X80HD D00YYY Y, Sony specified one of the OEM vendors designed for the mainland market, Sony Waterland.

Multi Media Masters (KingPro): Code Similar South Asia, CD-R 80min A001-1, Shulan is mostly.
Mr.Platinum Postech: CD-R 80min MHPEARL B00Y-Y, Waterland is a lot. (Temporarily omitting the manufacturer ring code n) After reading the introduction above, I believe that everyone has a certain understanding of the manufacturer of the disc's disc, and then talk about the author after purchasing N brand junk discs. Little experience.
There are three packages forms when the disc is finally sold on the counter:
1. Bulk, usually 50 pieces or 100 pieces each plus one to three protective cards with plastic film; 2. Round plastic pudding, usually 5 pieces, 10 pieces, 25, 50, 100 pieces Packing, etc. 3. Plastic boxed, usually single or double-piece, etc.
The disc produced by the same manufacturer is generally the quality of the box is better than the barrel, the bucket is better than bulk, the price of the boxed disc is more expensive, and there is more fakes. If a large number of use for personal users, the economic tolerance is the ability. I have to give priority, so we should give priority to buy a bucket disc.
The drum disc is not a hundred percent of the fake, try not to believe in the flowers of the merchant while buying, must open the bucket to see the disc, see the print layer of the disc (Note: the disc from bottom to top Whether the base, dye layer, reflective layer, protective layer and the printing layer) are exquisite, whether the writing is clear and unruly blurred, but also look at several loop code in this bucket, and the ring code number of the genuine disc is one Two kinds, if there are three kinds, it is necessary to be careful, it is not recommended to purchase this bucket disc.
The author saw that there is no ten loop code in 25 buckets, and then look at the printed layer. The imprint is rough. It is obvious that the bucket disc is JS to use the order of the bare disk (Note: Naked disk is no printing The discs of the layer are bare trays from the production line, which is the quality of the manufacturer's quality inspection standards. It is divided into different quality grades, C-Class, C-class according to the more detailed standards. D-level, etc., where the A level quality is the best) privately use the disc printed machine printing of counterfeit discs, the quality of purchase such disc is not guaranteed.
Purchase boxed discs should first check if the trademark on the box is exquisite without opening the packaging, whether the writing is blurred, if the trademark is printed, it is very bad, and it will look at the box. The box of the genuine disc is made of good plastic. The boxes of several cents sold in the non-general market can be compared with the left and right hands to hold the bits and gently screw it in the opposite direction. The box of the disc is generally very textured and is not easy to deform. The box used by the counterpart is like a cardboard. If the above two are passing, the box is going to open the box to see the disc test is ordered. After all, we buy The disc is not a box ^ _ ^.
However, some merchants will open the discounted disc will be opened, so I don't let you open the disc. So I have to use the last trick, I will ask the stone, and I will ask the merchant. If it is a fake disc JS, it is generally It is absolutely true that it is absolutely true that it is really true. At this time, JS's expression and eyes are not so natural. However, some merchants are also very confused. They also don't know that they sell the discs are really false. You can buy an exploration road first. If it is fake, you can ask the merchant to return. For the market's comparative classic boxed discs such as HP's C7999A, Kodak's true gold disc can also simply judge the truth through the quotation of the merchant. If the price is more expensive, there is a very small and source of supply The sufficient words are likely to be fake, the real business is not easy to shoot at a low price, can not sell themselves :(.
Finally, talk about the experience of the bulk disc, the price of bulk discs is enough, as long as I choose to be the choice of the poor people, I will purchase the bulk disc in accordance with the purchase method of the bucket disc. Bulk discs are generally deformed because of packaging and transportation, and the top and bottom of the following generals generally deformed. It is recommended to buy five discs to buy. Also, the bulk disc will have a labeling capacity, the record speed, and the actual capacity, the burning speed does not match, one case, such as marking 74min, 4-speed CD-RW disc, actually 80min or 12X, labeling 80min The disc, the actual capacity is 90 min (commonly discounted in Sast), and the discs in accordance with the above cases are generally JS, which is printed by JS using CD printers. Another situation is a labeling capacity of 80min730m (or 74min680m) The actual capacity is 80min700m (or 74min650m), because the manufacturer is considered 1m of 1000000, and the computer is considered 1m of 1048576, so the disc labeling 730m = Computer 700M identified. In addition, the genuine CD-RW disc except for the random disc except for bulk or bucket. After reading the introduction above, I believe that everyone has a certain understanding of the disc 's code recognition manufacturers. In this case, it will not discuss the quality of which manufacturer produced by the disc, so as not to go out, it is unknown. The material attack ^ _ ^, choose a famous brand or large manufacturer's genuine disc, quality is still guaranteed, try not to choose a low-speed disc, may all be stored in stocks without selling backlogs.
