ABSTRACT:
An optical disk apparatus which subsidiarily moves a feed at kick seek, thereby performing a tracking control is constituted to calculate a reference feed shifting amount and a compensation amount of the feed shifting on the basis of a lens offset just before starting of the kick seek and the number of tracks on an optical disk by which the lens is moved by the kick seek, further add/subtract the compensation amount to/from the reference feed shifting amount on the basis of the direction of the kick seek, thereby calculating a feed shifting amount, and subsidiarily move the feed by the feed shifting amount in concurrence with the kick seek. Thereby, tracking after the kick seek can be performed stably.
