ABSTRACT:
The amount of inclination of an optical beam relative to the surface of an optical disk as a target is detected by a disk inclination detector. When a track jump instruction is generated, a track jump controller determines whether or not the inclination amount is within a predetermined range in which tracking control and a track jump operation can be performed in a stable manner. If the inclination amount is within the predetermined range, the track jump operation is started. As a result, the track jump operation to a target track can be performed in a stable and reliable manner.
