PURPOSE:To facilitate adjusting operation and to make a fine adjustment by adjusting a head supporting member which supports a head supporting part movable in a track change direction to and from a rotary supporting part for a record carrier in at least two derections. CONSTITUTION:The reverse surface of a supporting member 73 is supported at three points by adjusting screws 81a-81c and the member is pressed by springs 84a-85 toward the adjusting screws 81a-81c from its top surface side. Further, it is supported by adjusting screws 82a and 82b, as well as 83a and 83b at right angles to the adjusting screws 81a-81c. An adjustment in the direction of the axis of sheet rotation is made by the adjusting screws 81a-81c, an adjustment in the tangential direction of the sheet rotation is made by the adjusting screws 82a and 82b, and an adjustment in the radial direction of the sheet rotation is made by the adjusting screws 83a and 83b. Further, an azimuth adjustment is made by an eccentric pin 61. Thus, the magnetic head 51 is adjusted in every direction to the sheet supporting member 72 and magnetic sheet 71 by the adjusting screws 81a-83b and eccentric pin 61. |
