ABSTRACT:
A tracking control apparatus having a track jump detection device and a memory for storing driving signals for the tracking control detects a track jump, and when such a track jump has occured, makes the tracking control inoperative, decelerates the velocity of light beam caused by the track jump by driving a voice coil motor using signals inverted from the signals stored in the memory, and, thereby, restarts the tracking control quickly.
