Optical disk drive apparatus.

摘要

An optical disk drive apparatus used for driving an optical disk having tracks for storing and recording information employs an optical head (3) which focuses a light beam onto a spot on a track on the optical disk. An actuator (4,5) moves the head, to bring the spot of the light beam from its current track to a target track in order to access the target track. A track counter (27) counts the tracks moved by the spot of the light beam during the access operation but the track counting operation is disabled by a masking pulse (S15) for an interval at the start of each track access operation.
