ABSTRACT:
Clock pulses are generated at a frequency having a fixed relation with a rotation of an information recording disk formed with a track. The clock pulses are counted. A first kick pulse is generated when the counting of the clock pulses starts. A tracking error signal is generated. A detection is made as to whether the tracking error signal crosses a zero level after the first kick pulse is generated. A brake pulse is generated when the tracking error signal crosses the zero level. A second kick pulse is generated when a number of the counted clock pulses reaches a predetermined number.
