Abstract
PURPOSE:To suppress the overrun of a slider by searching a stoppage distance corresponding to the present speed of the slider, and drawing conclusion based on a remaining distance in which a start point to apply brake on the slider is corrected and the movement of the slider due to inertia. CONSTITUTION:Stoppage distance data required for the stoppage of the slider 3 by attaching braking force on a driving motor 14 is obtained in advance at every speed at the brake start point of the slider 3. And the slider 3 is moved to an object track, and the number of tracks traversed by a pickup 2 is integrated, and the present track position and the remaining number of tracks to the targeted track are obtained, then, the present speed of the slider 3 is detected, and the stopping number of tracks at the present speed is searched from the stoppage distance data, and when the remaining number of tracks coincides with the searching number of tracks, the braking force is attached on the driving motor 4, then, the slider 3 is decelerated. In such a way, it is possible to suppress the overrun of the slider 3 without decreasing the speed of the slider.
