Abstract
A system and method for preventing effective copying of digital recordings. A copy-state code accompanies each recording, one state of which represents that no copies at all are to be made of the recording. Compatible players are designed to prevent play of any writable disk which includes a «no-copy» code. It is the inconsistency between the code and the medium containing it that causes play of the medium to be inhibited.
