Patent DE-4103827-A1 (DE)
Inventor: BAAS DIETER
IPC: G11B20/10
Filed: 1991-02-08
Abstract: Data-reproduction device which reads data from a disc rotating at constant linear velocity. CD players read data from a compact disc turning at constant linear velocity, each compact disc having its own specific track-scanning speed. CD players exist which determine the track-scanning speed specific to the compact disc to be played. In order to shorten the time interval between inserting the compact disc and start of play, the invention calls for the player to be fitted with a memory unit (S) capable of storing the individual track-scanning speeds of several different discs (CD). Since the individual track-scanning speed is stored, it does not need to be determined again when a disc which has already been played once is inserted. The invention is of use in CD players, video disc players, DRAW disc players and magneto-optical recording and replaying devices.
