CGMS

Short for Copy Guard Management System, CGMS is a method of copy protection used to prevent unauthorized disc copying. The Copy Guard Management System first determines if data recorded on a recording medium is original or copied, and then prevents the data from being copied when it is not original. A copy of the original can be made only once, but a copy of data (secondary copy) cannot be copied again. May also be called Single Copy Management System (SCMS).
