ABSTRACT:
A head control apparatus of the invention includes a moving unit for moving an optical head to a given information track on an optical disk having concentric information tracks, a detector for detecting a direction of movement of the optical head from the a signal reproduced from the optical head, and a controller that, when the detector has detected the direction of movement of the optical head, controls the moving unit so that the optical head may move to a specified information track at a first speed, and that, when the detector has not detected the direction of movement the optical head, controls the moving unit so that the optical head may move to a specified information track at a second speed slower than the first speed.
