Abstract
PURPOSE:To prevent the generation of a track shift at the time of kick so that a light spot can be operated exactly and stably in a short time to a desired track, by executing a kick operation after having eliminated substantially a relative moving speed in the information track direction of an optical head and a recording medium. CONSTITUTION:On the information recording surface of an optical card 1, many information tracks 4 extending in the LF direction are arrayed in parallel. Information is recorded and reproduced by inserting the optical card 1 into a recording and reproducing device 19, and while bringing the optical card 1 and an optical head 18 to a reciprocating motion relatively in the direction of the information track 4. When an access to a target track is ended, a kick operation is executed, and before moving a light spot to the next adjacent track, the optical head 18 is decelerated. A moving speed of the light spot, that is, the moving speed of the optical head 18 is detected by a detecting circuit 70, and at the time point when time (t) has elapsed after the moving speed has become '0', a kick instruction is outputted to a kicking circuit 71 from an MPU 10, and a kick operation is executed.
