ABSTRACT:
The invention calculates the number of track crossing signals to be counted until a target position is reached without an actual seek operation, thus making it possible to complete a seek operation in a short time and without the need of the additional seek operation disclosed in the related art. A memory means is provided for storing the relation between the number of tracks (Delta t) from a current position to a target position and an indicator of the movement of said optical head toward said target position. A control means is provided for calculating the number of track crossing signals to be counted during a seek operation based on said stored relation when the target position is given, and for generating a control signal causing said optical head to seek based on the number of the calculated track crossing signals.
