Abstract

PURPOSE:To increase the control accuracy of an light-inputting-receiving head and to speed up an access control by counting the number of track which an radiating light from the light-inputting-receiving head crosses at the time of an access action, confirming the moving quantity, simultaneously, driving an actuator and stopping a tracking control after a prescribed time after the light- inputting-receiving head is started to move. CONSTITUTION:When an access instruction is executed from an operating part M6 and light-inputting-receiving head is started to move in a goal track direction, the number of tracks which the irradiating light from a light-inputting- receiving head M1 crosses is counted by a number-of-tracks counting means M8 based on an error signal from an error signal generating means M4, and a driving means M9 drives an actuator M3 while confirming the actual moving quantity by the counting number. Here, after the prescribed time passes after the driving of the actuator M3 is started by the access instruction from the operating part M6, the action of a tracking control means M5 is stopped by a tracking control stopping means M10. Thus, the accuracy of the moving control of the light-inputting-receiving head can be improved, and the access control can be speedily executed.
