An optical disk apparatus has an optical head for photoelectrically detecting track data and a track jump data component corresponding to an accidental track jump on an optical disk. A circuit is provided wherein the track jump data component is detected from the data detected by the optical head so as to determine the number of jumped tracks and a jump direction therefrom. A tracking section performs tracking control of the optical head in accordance with a signal corresponding to jump direction and the number of the jumped tracks and returns a laser beam to the track at which the laser beam was directed before the track jump.
