摘要: A tracking control device for controlling a position of beam spot formed by converging light on disk having tracks thereon includes: an actuator moving the in direction substantially perpendicular to tracks; error detecting circuit deviation from one using returning and outputting signal indicative detected deviation; section driving drive accordance with so as be positioned tracks. When is saturated, obtains saturation amount saturation, delays signal, supplies together signal.
