A recording/reproduction element is mounted on a magnetic head slider via a piezoelectric element so that a displacement of the piezoelectric element performs fine control of the position of the recording/reproduction, thus enabling fine spacing and high tract positioning accuracy. This improves linear recording density and track density. A pair of electrodes are formed on both sides of a piezoelectric element to constitute a piezoelectric actuator. One electrode is arranged opposite the rear surface (air flow out end) of a magnetic head slider 11. A recording/reproduction element is arranged on and electrically insulated from the other electrode. The piezoelectric element includes a piezoelectric element displaced in a spacing direction, enabling fine spacing control, a piezoelectric element displaced in the track direction, enabling fine track position control, and a piezoelectric element displaced in a magnetic disc rotation direction, enabling reduction of jitter of a reproduction signal.
