An optical disk playback device includes a control means (an LSI 5 for system control) for performing a track search according to contents information, comparing a current track start point position at the time after performing the track search with a target track start point position, when the comparison result shows that they differ from each other, setting up a new target track start point position by performing a predetermined arithmetic operation, then performing a track search again, and, when a new current track start point position at the time after performing the track search again matches the set-up new target track start point position, starting a playback from the new current track start point position.
