。[Claims for Utility Model Registration] In a magnetic disk reproducing machine configured to be able to reproduce signals from a magnetic disk having a plurality of signal recording/reproducing tracks, when a signal is reproduced, a magnetic head for picking up a reproduced signal is used to record the signal. /A tracking device provided for positioning the track to follow the reproduction track, the tracking device being arranged so that the sum of the maximum value and the minimum value of the interval between the upper and lower envelope outlines of the reproduction signal becomes substantially maximum.
A tracking device for a magnetic disk player, characterized in that the tracking device is configured to automatically adjust the position of the magnetic head for picking up the reproduced signal.
