The first point: Look at the black ink on the round laser anti-counterfeiting label on the cover. This black ink is easy to scrape off with your nails. ) There is an invisible bar code on the black ink of the genuine label, which can be seen by side light and sometimes felt by hand. Piracy is black, it is not easy to scrape off, and there is no invisible bar code.
The second point: take out the CD and observe the data layer (that is, the mirror) carefully. In the boot area, the name and version number of the CD are on the bright ring near the center of the circular hole of the CD. See if this set of data is the same as the data on the record jacket. The genuine product should be the same.
The third point: the real optical disc coding has a tiny protruding IFPI near the center of the circular hole of the optical disc. Those without codes or with grooves or hot stamping marks in that position are pirated.
IFPI code, formerly known as SID code, is a standard formulated by Philips. It is an IFPI organization (that is, the International Federation of the Recording Industry, the full name of which is "International Federation of the Photography Industry") and an international organization representing the global recording industry. Its members come from more than 500 record manufacturers and distributors in 76 countries around the world, occupying most of the global music market share, and also have 46 national associations.
These five world-famous record companies are all members of the International Federation of Phonographic Industry (IFPI), which has launched a set of standardized anti-piracy procedures. This is the industry standard to identify the source of CD production and reproduction, and it gives each manufacturer a unique ID. Ordinary genuine CDs and high-density optical discs, including DVD and SACD, are engraved with this code.
On the basic code of domestic CD reproduction
With the improvement of domestic optical disc manufacturing technology, most domestic manufacturers of imported versions have turned to domestic production from Hongkong, Taiwan Province and Japan. The sound quality of a CD depends not only on the quality of the master tape, but also on the reproduction process of the CD. In the process of producing genuine CDs in the world, most CDs after 1994 have SID codes to indicate the origin of CDs. Therefore, SID code is very important to distinguish genuine and pirated optical discs, and it is one of the important guarantees of optical disc quality. At present, there are nearly 80 CD reproduction units in China. The following is their list (this list is incomplete and needs to be further supplemented and improved), which is believed to be helpful for fans to identify piracy and understand domestic manufacturers.

At present, most domestic manufacturers have IFPI codes, which are required to be attached to the production line molds and are not easy to disassemble and replace. This code is used to identify the replication source. The code of pirated CDs is afraid to appear. If this code appears in piracy, find out which assembly line is pressed out, hehe, this line will be scrapped. . . . .
Therefore, in general, when cam- is made, IFPI code will be burned with an electric soldering iron. This is the trace of uneven glue in the middle of the CD when we bought a few dollars.
ISRC- International Standard Coding for Audio-visual Products
This code will be the only international identification code of another kind of knowledge products-audio-visual products, just like the International Standard Book Number (ISBN) of books and the International Standard Book Number (ISSN) of periodicals.
Capital letter "ISRC" is an indispensable symbol for the coding of international standard audio-visual products. Country code, publisher code, record year code, record code and record item code are five data segments that make up ISRC code. Paragraphs are separated by the last hyphen "-". The total length of the five data segments is 12 characters, which is a fixed-length coding structure with no parity bits.
(1) country code The code of the country where the audio-visual publishing house is located, consisting of two capital letters. It is given according to the international standard ISO3 166 "country and region name code". For example, SE=SWEDEN (Sweden) CN=CHINA (China).
(2) The company code is the company code that owns the first copyright of the audio-visual product, also known as the first owner code, and consists of three characters, in which the number ranges from 0 to 9, the letter ranges from A to H, J to H and P to Z. The letters "I" and "O" are included to avoid confusion with the number 1 and 0. Generally speaking, three characters should contain at least 1 letters or numbers. According to the permutation and combination planning calculation, the publisher code of a country can be set to 3× (10×10× 24+10× 24× 24) = 24824 (sheets).
(3) The recording year code is the year code when the audio-visual product is recorded or launched, and the last two digits of the year are taken. For example, 92 stands for 1992, and the video year code is determined by the audio-visual publishing house.
(4) The recording code identifies the sequence code of an audio-visual product in the recording year, which is set to 3 or 4 digits by the publisher.
(5) Recording item code identifies the code of each independent program in an audio-visual recording, which consists of 2 digits or/kloc-0 digits.
The category code in Chinese standard audio-visual product coding consists of two parts: record type code and subject classification code, which are separated by China point.
Record type code: a capital letter, a or v.
Audio recording (audio)
Video recording (video)
The classification code is given according to the basic classification number of Chinese Library Classification, such as music category J6 and film category J9 in art category.
Take the "Xuanqu Mandi1"ISRC code produced in Bai Fei as an example:
CN-F28-02-795-00/A.J6
CN is China, F28 is the publisher, 02 is the production in 2002, 795 is the serial code, 00 is the overall recording code, and A.J6 stands for music audio disc! ! !
