PURPOSE:To obtain a high-quality picture at the time of the slow reproduction and the even-fold velocity by fixing one end of the piezoelectric element in the magnetic head device along with the head element provided to one free end of the other end of the piezoelectric element and the head element of different azimuth angle provided to the other free end respectively. CONSTITUTION:Electrode 3-3 is provided across piezoelectric element 3-2, and these two sheets of electrodes are stuck together to secure the bimorph structure. One end of the electrode is fixed via fixing tool 3-4, and head element 3-1A is provided to one free end along with attachment of head elements 3-1A and 3-1B of different azimuth angles at the other free end respectively. Thus the relative position can be controlled between magnetic heads 3-1, 3-2 and the magnetic tape by controlling the deflected voltage applied to element 3-2. And only the heads of the same azimuth angle are used to reproduce only the tracks coinciding with the angle. Thus the flicker can be prevented on the screen in the case of the still reproduction. Furthermore, a reproduced picture free from the flicker can be obtained as in the case of the still reproduction also in the case of the slow reproductin and the even-fold value. |
