Abstract
PURPOSE:To search an object address in a short time by calculating the number of tracks to an object track based on a difference between the present addresses obtained just before and immediately after a jump operation and a jumped number of tracks, and searching the object address by performing the jump operation again. CONSTITUTION:The jump operation which drives a tracking actuator until the number of tracks to be jumped at the detecting point of information arrives at a prescribed value setting a tracking servo loop at an OFF state corresponding to a search command is performed. And the number of tracks from the present track where the detecting point of the information immediately after the jump operation exists to the object track is calculated based on the difference between the present addresses obtained just before and immediately after the jump operation and the jumped number of tracks, then, the targeted address is searched by performing the jump operation again. In such a way, it is possible to perform the search of the object address in a short time.
