TECHNICAL CD INFORMATION

Short run CDs in small quantities are often burned (one-offs), as opposed to the more reliable standard method of replicated CDs (injection-molded). IN higher quantities, there is minimal price difference. Replicated CDs look better too. Reliable plants are all ISO-9002 compliant.

ISRC ( International Standard Recording Code)

http://www.ifpi.org/online/isrc_intro.html

International Standard Recording Code. Some recorders allow the ISRC to be recorded for each audio track on a disc. The code is made up of: Country Code (2 ASCII characters), Owner Code (3 ASCII characters), Year of Recording (2 digits), Serial Number (5 digits).

Owner Code aka Registrant Code is the code of the 'producer': The Registrant Code is assigned by National ISRC Agencies upon application by the producer.

Serial Number may be chosen by yourself, eg. catalog number.

ISRC can be used to track the original copyright holder in cases of piracy.
