ABSTRACT:
A tracking apparatus applicable to a rotatable magnetic recording medium which is provided with a plurality of discrete tracks thereon includes a head for sensing signals out of the tracks, a head transport mechanism for moving the head to a position on a desired one of the tracks, an envelope detector for detecting an envelope of signals sensed by the head, and a controller for performing tracking by controlling the head transport mechanism responsive to the detected envelope. A sync signal generator circuit is provided for producing a reference signal which is synchronous to the rotation of the recording medium. The controller controls the head transport mechanism and causes the envelope detector to detect an envelope, responsive to the reference signal.
