ABSTRACT:
A tracking servo system of disk player uses the time difference detection method for generating the tracking error signal. A time gate is provided for detecting the zero-crossing of the tracking error level in an on-track condition during a jumping operation. As the result, negative effects due to unstableness in timing of the zero-crossing can be eliminated.
