Method for deciding the direction of pick-up head of disk driver while crossing tracks |
摘要 |
A method for determining a track-cross direction of a pick-up head of an optical disk drive includes the following steps. (1) When a track-cross velocity of the pick-up head was determined to be greater than a predetermined velocity, it is determined whether the track-cross velocity of the pick-up head is changed to be less than the predetermined velocity. If not, the track-cross direction remains unchanged. (2) When the track-cross velocity of the pick-up head was determined to be less than the predetermined velocity, it is determined whether the track-cross velocity of the pick-up head is changed to be greater than the predetermined velocity. If not, the track-cross direction is determined according to a phase difference between a first track-cross signal and a second track-cross signal.
