Method for judging track jump direction, method and apparatus for controliing track jump of optical record/player

摘要

land / groove (Land / Groove) relates to a track jump control method and apparatus of the recording system, detecting the vibration direction of the tracking actuator with a phase difference of the two signals outputted from the track when the track jump direction and divided into two light detection elements and the vibration reaches the desired track in the opposite direction of the detected tracking actuator means that a tracking error signal by reverse phase as to generate a brake suppressing the vibration waveform of the tracking actuator , a land / groove recording method in the mirror signal can be carried out without a stable track jump .
