Abstract

PURPOSE:To enable a quick random access by making the maximal use of the driving force of a slider motor in an acceleration area, and maintaining the delecerating speed of a slider in such an ideal deceleration that the moving speed of the slider itself does not vary in an oscillating manner. CONSTITUTION:A pickup 2 detects information from an information detecting spot which is freely rockably in relation to a 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 rate for the slider 3 in the deceleration stage is controlled to approach an ideal deceleration in a constant value, or controlled to an ideal deceleration rate corresponding to the decreasing number of remaining tracks. As a result, a quick random access is made able.
