The piezoelectric actuator 18 is formed by laminating an electrode comprising a conductive film and an piezoelectric film, and driven in a d33 mode. Also, the slider 18 is formed into a tapered shape in which a magnetic head 13 side is thin and the opposite side is thick. When the recording medium (magnetic disk) is rotated, the slider 14 floats by an airflow and an extension direction of the piezoelectric actuator 18 is tilted relative to a magnetic disk plane.
