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.

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.

Abstract: An apparatus and method generate an adaptive track zero crossing signal in a disc drive. An adder adds and outputs a predetermined signal to generate a track zero crossing signal and a correction signal. A comparator having a first input node and a second input node, receives the predetermined signal from the adder through the first input node, receives a reference voltage signal through the second input node, compares the signals input into the first and second input nodes, and generates a track zero crossing signal having a square wave. An offset correction calculator measures lengths of high and low sections of the track zero crossing signal, calculates a ratio of differences in the lengths between the high and low sections, and generates a correction signal to maintain a duty ratio of the track zero crossing signal at a predetermined target value using the calculated ratio.
