ABSTRACT:
A method and associated apparatus for identifying, to manufacturing test equipment, copy protection information contained on a compact disc (CD). The method includes adding data in standardized industry formats to unused sectors of a CD and providing the capability to test equipment to read the data. The added data is unreadable and ignored by conventional compact disc readers and compact disc drives. The added data is defined by manufacturers and users of copy protection techniques. Additional copy protection verification can be accomplished by using specialized verification tools.
