出装置。Tracking servo means is provided to control the deviation of the recorded information detection point in a direction substantially orthogonal to the recording track so that the recorded information detection point accurately follows the recording track, and recording is performed so that the track linear velocity is constant. A group lock escape device for a recorded information reproducing device for reproducing a recording disc, comprising means for applying a disturbance to the servo loop of the tracking servo means when a time axis error of the reproduced information exceeds a predetermined value. Features a group lock escape device.
