摘要

When controlling a search for a target track on an optical disk having tracks on which data are recorded, the track-search control apparatus determines whether or not the optical disk is a DVD-RW disk. Then the apparatus calculates the number of tracks between the position of the currently detected track and the position of the target track, and calculates the number of correction tracks with which to correct the calculated number of tracks when the optical disk is determined to be a DVD-RW disk. Further, the apparatus executes the search for the target track based on the calculated corrected number of tracks.
