How to distinguish between genuine and pirated CDs

Just like the logo of laser anti-counterfeiting, it can only be barely seen through different angles of light, and it is also distributed to the whole disk every 60 degrees. Description and quality assurance (or investigation) are impossible. The instructions are beautifully printed and legible. If the instructions on the disk are not as clear as those printed in ordinary game magazines, you should be extra careful. Instructions usually don't design the plot of the game, just some basic operation methods. The original disk can be identified from the following aspects: 1. Generally speaking, the price of genuine CDs is higher, while the price of illegal audio-visual products is generally lower than that of genuine audio-visual products with the same content because they are produced at almost zero cost without paying the page fee. 2. Look at the common pirated products in the publishing market. They will pretend to be the following companies: Fujian Changlong Film and Television Company, Changjiang Audio and Video Publishing House, Tianjin Audio and Video Publishing House or Tianjin Audio and Video Company, Guangxi National Audio and Video Publishing House, Guizhou Oriental Audio and Video Publishing House, Ningxia Dida Audio and Video Publishing House, Qinghai Kunlun Audio and Video Publishing House, Jilin Changbai Mountain Audio and Video Publishing House, Xinjiang Audio and Video Publishing House, etc. These audio and video publishing units have no import qualifications, nor have they been approved by the Ministry of Culture to introduce overseas music products. 3. Look at the color printing of the genuine packaging. The colors are rich and soft, with distinct layers and clear handwriting. Under the front of the color seal, there are the publisher's logo and CTHE logo or manufacturer's logo. There is usually a CTHE logo on the back of a colored seal. The DVD is not the area marked with "6", but the whole area. Generally speaking, as long as you look directly at the packaging, you can basically recognize that it is not genuine. 4. Look at the SID code. SID code is the source identification code of laser digital storage film, and it is an unadjustable identification code that coexists with the production line. SID code is universal in the world, and laser discs without SID code are illegal audio-visual products. SID code consists of a capital English letter and three Arabic numerals, plus handwritten "IFPI" (there is an arc above the four letters). If there is no SID code, it must be illegal audio-visual products. The SID code of the copy processing unit that cooperates with Sino-Shandong Degara is: Beijing Luwen Laser Technology Co., Ltd. IFPIJ200-J 214; Shanghai Xinsuo Music Co., Ltd. IFPI X400-X407；; ; Dalian Lu Hua Audio-visual Industry Co., Ltd. IFPIZ200-Z209. Pirated CTHE products generally have no SID code or the above SID code. 5. Look at the identification code Generally speaking, according to the relevant regulations, the outer packaging of genuine audio-visual products generally has an internationally unified ISRC code, "National Rights Image xxx" registered by the National Copyright Administration and the approval number of the Ministry of Culture "Wen Xiang Gold [2003]XXX". Audio-visual products imported without approval number or forged approval number and published abroad are illegal audio-visual products. The ISRC code, copyright authentication number and drawing number of pirated products are incomplete or unmarked. 6. Look at the quality of genuine audio-visual products, and the title has the name and logo of the publishing house.
