ABSTRACT:
A player system for a video disk or a compact audio disk in which the time to move the pickup to the start of a playing position of a selection other than at the beginning of the disk is considerably reduced. The pickup is first moved to a position substantially at the middle of the area containing recorded information on the disk in a single quick motion. Then a search operation is begun for the address of the desired selection. The speed of the disk is also controlled so that when the pickup reaches the middle of the disk playback can begin immediately.
