PURPOSE:To remove the skew of a rotary magnetic head and to improve the reliability by constituting a supporting device around a rotor motor supporting member fixed to a base through elastic parts. CONSTITUTION:The rotor motor supporting member 20 which supports a rotor motor 4 and a head rotor 3 on the base 19 fixedly at specific positions is provided with the 1st elastic part 21 and the 2nd elastic part 22. The 1st elastic part 21 consists of a rectangular groove 27 in an Y direction, and the elastic part 22 consists of two Y-directional grooves 28 and 29 provided in both surfaces of the rotor motor supporting part 20 closely while facing each other. Then, the direction and amount of a skew are detected, and a cam driving motor 24 is controled by using the signal of a rotation angle position detector 26 so that the skew is cancelled, slanting the head rotor 3 in a direction A or B. Thus, the supporting device is provided with the elastic parts to remove the skew through the simple constitution, improving the reliability. |
