ABSTRACT:
A compact disc having digitally encoded, reproducible data recorded in tracks on a playing side and having an editing device for storing order of play data to control the sequence in which the tracks are played is provided. The editing device can be on the nonplaying side of the compact disc. A compact disc reproduction system, specially equipped to play discs having editing devices thereon, has a read/write head for reading order of play data from the editing device and for selectively encoding the editing device with order of play data. An internal memory stores order of play data in the disc player. Alternatively, the editing device can be a separate item from the compact disc, to be inserted in a reader on the reproduction system. Another preferred compact disc player plays conventional discs loaded therein by scanning each disc to receive data for identifying the disc. The identifying data can be the number of tracks and the duration of each track on the playing side of the disc. Alternatively, it can be an identification code enscribed on the disc surface. This disc identification data is compared with identification data stored in a memory to determine whether order of play data has already been stored for the disc. Upon detection of a match, a central controller looks up the order of play data assigned for the disc and commences play according to the preprogrammed sequence.
