description	A magnetic head, rotating at high speed in a reproduce relationship with a magnetic tape, is supported on the free end of a piezoelectric bender element. The bender element is caused to vibrate between two limits at a fixed frequency (dither) to determine the instantaneous position of the magnetic head relative to a track of data recorded along the tape. A feedback servo provides continuous adjustment of the position about which the transducer is vibrated so as to maintain the magnetic head in an optimum reproduce relationship with respect to the track.
