Abstract
PURPOSE:To simplify a process of manufacture with the need for the wiring of a circuit eliminated by providing an electric signal detection part to the tip of an electro-mechanical converting element using piezoelectric plates, by controlling the position by a driving voltage applied across the converting element, and by providing a driving circuit for the driving voltage on the piezo-electric plate. CONSTITUTION:Bimorph plate 11 for magnetic head unit 12 for a video tape recorder is composed of an electro-mechanical converting element using two piezoelectric plates 13 and 14. To the tip of bimorph plate 11, video head 16 is fitted which records and regenerates video signals, and its base end part is fixed to rotary drum 18 via head base 17. Further, storage gauge 19 is bonded nearly in the center of bimorph plate 11. On part of the surface of piezoelectric plate 13 of bimorph plate 11, a conductive metal layer as an electrode is removed and circuit elements 30, 33, 34, 35 and 37 are integrally provided which constitute a bimorph driven circuit part, recording regenerative head amplifier circuit, displacement detection circuit part, etc.
