ABSTRACT:
A method and apparatus for canceling noise from track cross signal includes binarizing the track cross signal with reference to at least two reference values, and removing noise from the binarized track cross signal based on a command speed according to which a tracking actuator moves a pickup. Accordingly, it is possible to remove noise from a track cross signal so as to obtain information regarding precise speed of track searching or position on the track, irrespective of the searching speed.
