<p>A magnetic head supported for scanning a magnetic medium along tracks is mounted on a piezoelectric bender element for movement lateral to the tracks as they are scanned. As the head scans a track, the relative position between the track and the head is sensed to determine the head's tracking position. A bias control signal is generated by a servo circuit and applied to energize the piezoelectric bender element to posit on the head relative to the track to maintain the head in the desired tracking position as it scans the magnetic medium.</p> |
