OPTICAL DISK DRIVE APPARATUS HAVING COUNTER DISABLE AT SEEK START-UP |
摘要 |
In an optical disk drive apparatus for driving an optical disk having tracks for recording information, an optical head focuses a light beam onto a spot on a track on the optical disk, and an actuator moves the optical head, thereby causing the spot of the light beam to move from its current track to a target track in order to access the target track. A track counter counts the tracks moved by the spot of the light beam. The counting of tracks is disabled for an interval at the start of each track access operation to prevent miscounting caused by jitter that occurs when initiating a track access operation. |
