Abstract

PURPOSE:To enable a quick random access by deciding the timing of the switching of a slider from accelerating area to decelerating area by a specified method. CONSTITUTION:A pickup 2 detects information from an information detecting spot which is freely rockably in relation to the slider 3. The slider 3 is driven by a quick-response drive motor 14 and moves back and forth in the radial direction of a disk 1. The slider 3 is driven to quickly cross tracks through an acceleration stage in which it 3 is accelerated up to a high speed and through a deceleration stage during which it 3 is decelerated. The deceleration characteristic at the time of supplying a brake force to the slider motor 14 is preliminarily obtained, also a current speed of the slider 3 as well as an accumulated number of tracks is obtained, and based on the results of these, the timing of the switching from the acceleration phase to the deceleration phase is calculated. As a result, a quick random access can be made able.
