PROBLEM TO BE SOLVED: To provide an optical disk playback method in which track jump or pull-in to a playback track can be performed surely. SOLUTION: When pull-in to the playback track is started (step S103), not only OFT sensitivity adjustment is performed in loading of the optical disk (step S102), but also OFT sensitivity is adjusted (step S 104) by obtaining a slice level based on an OFT signal even during track jump processing.
