Abstract

PURPOSE:To perform appropriate search corresponding to a distance and to realize quick random access by selecting the acceleration/deceleration speed moving control mode and the constant speed moving control mode of a slider corresponding to the distance from the present address to a targeted address. CONSTITUTION:The distance from the present address to the targeted address of a pickup 2 is detected, and when a detected distance is larger than a prescribed value, a tracking loop is turned ON by obtaining address data by the constant moving control mode, that is, a signal from the pickup 2 and performing the constant speed moving control of the slider 3 after executing the acceleration/deceleration speed moving control mode. When the detected distance is smaller than the prescribed value, the tracking loop is turned ON after executing the constant speed moving control mode without executing the acceleration/deceleration speed moving control mode. In such a way, it is possible to execute the quick random access.
