Abstract
PURPOSE:To execute a kick stably and exactly by a kick pulse whose crest value is small, by switching plural times a switching pulse for switching the tracking polarity, so as to correspond to phase of a kick pulse for kicking a reproducing stylus on a disk-like information recording medium. CONSTITUTION:When a kick pulse for kicking a reproducing stylus 4 on a disk- like information recording medium 1 has been generated from a kick pulse generator 12, a polarity switching pulse generated from a switching pulse generator 11 is switched to a high level from a low level. Accordingly, the reproducing stylus 4 becomes an astable tracking state, and moves to one adjacent track in a free state. Subsequently, when the reproducing stylus approaches the center of a prescribed track, a kick pulse being opposite in polarity is provided as brake force, simultaneously the switching pulse is changed to a low level, and force being reverse to the track direction is put on additionally. After that, when the reproducing stylus 4 reaches a stable point of the track, said pulse is changed to a high level again, and a kick is executed by a kick pulse whose crest value is small.
