PURPOSE:To execute a still reproducing of the same field by two heads without increasing the number of magnetic heads by providing the magnetic head and a driving means for rotating and displacing its head and changing an azimuth angle. CONSTITUTION:At the time of recording and usual reproducing, a head base 2 to which a magnetic head 1 is installed is rotated clockwise by a spring centering around an intersection point O and made to contact by pressing to a stopper 4. An R head 11 and an L head 12 are fitted to a rotary cylinder 10 at an interval of 180 deg., and at the time of recording and usual reproducing, azimuth angles of the heads 11, 12 are opposite to each other, but at the time of a still reproducing, a current flows to an electromagnet 5 of one head of them, a magnetic material part 2b is adsorbed, the head base 2 is rotated, and the azimuth angle of the magnetic head 1 is varied. In this way, the azimuth angles of the heads 11, 12 coincide with each other and reproducing is executed, therefore, a reproducing picture having no blur can be obtained. |
