ABSTRACT:
A tracking control apparatus includes a memory for storing tracking control information of a previous track corresponding to a present position of a current track being tracking-controlled, and a tracking controller for generating a new tracking control signal by using a tracking error signal derived from the current track and stored tracking control information for the previous track, to thereby enhance the precision of tracking control of the present track even when the track is deformed. A corresponding method is also described.
