ABSTRACT:
An optical disk player having a tracking servo loop comprising tracking error signal generating means and tracking driving means for operating a tracking mechanism in an optical head based on a tracking error signal generated. In the tracking servo loop, a servo gain selector is installed to selectively provide a first gain suitable for a recording and/or reproducing operation and a second gain which is higher than the first, thereby keeping the second gain selected only during the period from the beginning to completion of a tracking servo positioning operation.
