发明名称 Disk reproducing method
摘要 A disk reproducing method, such as may be used with a compact disk or video disk, in which playing can be quickly restored following track flow caused, for example, by an external shock applied to the player. The disk is rotated with a spindle motor, the rotation of which is controlled with a first servo circuit. Data recorded on the disk is reproduced with a pickup. Tracking of the pickup is controlled with a second servo circuit. The pickup is driven with a slider motor radially of the disk. Rotation of the slider motor is controlled with a third servo circuit. When the first servo circuit is maintained unlocked for a predetermined period of time, the second and third servo circuits are turned off for a predetermined period of time, and then turned back on.
