& ltP> mold SID code. Each mold SID code consists of "IFPI" and four or five characters. When the manufacturer applies, IFPI organization will only allocate the first two characters (if the code is 4 characters) or the first three characters (if the code is 5 characters). The last two characters are assigned by the manufacturer to the molds corresponding to each production line. Because one character can represent 32 molds (10+26-4), two characters can represent at most 1024(32x32) production lines. Therefore, a manufacturer can have at most 1024 production lines. The code is required to be attached to the production line mold, which is not easy to remove or change. This code is used to identify the replication source. The mold SID code is located on the plastic sheet of the inner ring of the CD. According to the specification, IFPI should be capitalized, but at present, the IFPI numbers of domestic film bases are all lowercase, and imported discs are all capitalized. Therefore, it has recently been suggested that some discs are suppressed abroad and packaged at home. In fact, they can be distinguished according to the situation of IFPI. & ltBR & gt At present, most domestic manufacturers only have the mold SID code, that is, the SID code of the replication unit. Many genuine products on the market only carry the mold SID code, but not the master SID code, because the master does not carry the master SID code at all.
In addition, the IFPI codes of major tablet PC factories in Chinese mainland are attached.
