Reducing access time to selected CD track - reading identification data to achieve synchronisation with stored data

摘要

A CD loaded into a player is scanned by a laser (L) and the control unit (ST) operates to read the first `n' data sections of each music track. The data are entered into the memory (S) of the player. When the user wishes to playback a specific music track with values in the memory are read. The disc is operated in a search process until the track is identified. The data from the memory are synchronised with the data generated from the search to control the process. USE - CD, video and DRAW disc players or magneto-optical appts.
