Method of adjusting the track to photo ratio in an optical disc drive

摘要

The present invention discloses a method of improving seeking precision by adjusting the track to photo ratio in an optical disc drive. After a disk is tray in, the number of photos detected by the optical disk drive is pre-calculated when the optical pickup module is to seek a predetermined number of tracks. The actual number of seeking tracks performed by the optical pickup module is calculated after the optical disk drive has detected the pre-calculated number of photos. Thereafter an optimal track to photo ratio is obtained.
