ABSTRACT:
Provided are a method and apparatus for canceling noise from a track cross signal, a method for controlling an optical disc drive, an optical disc drive, and an optical disc reproducing apparatus. The method for removing noise from a track cross signal includes (a) removing noise from the track cross signal by binarizing the track cross signal with reference to hysteresis set values that are determined according to a command speed for a tracking actuator; and (b) removing glitch noise from the binarized track cross signal based on a predetermined time value. Accordingly, it is possible to effective remove noise to obtain information regarding the precise speed and position of a desired track.
