Abstract

PURPOSE:To enable the magnetic to vibrate toward the direction having azimuth, by mounting the rotary magnetic head on the slope equivalent to the azimuth provided on the rotating body. CONSTITUTION:On the upper surface of the rotating body 23, the angle set tool 24 having the slope with angle alpha equal to the azimuth, is placed and the piezoelectric element bimorph 15 is provided. Further, the head 7 is mounted at the tip of the bimorph 15 and it is retained with the fixture 25 and screwed with the screw 26. In this case, head gap is vertically provided to the surface of the bimorph 15 without providing the azimuth. With this constitution, when search vibration is made to the bimorph, the head 7 can be vibrated in parallel to the azimuth. Accordingly, no shift of time axis is caused. Thus, the setting of angle is made easy sine the head is mounted on the slope corresponding to the azimuth.
