Abstract

PURPOSE: To reduce the disadvantages such as the floating height of magnetic head and recording and reproduction characteristics changed every track, without loosing the characteristics of the rotary type positioning unit, by the magnetic head positioning unit locating each fulcrum axis so that each side constitutes parallelogram.
CONSTITUTION: The arms 111 and 112 are fitted rotational free at the shafts 101, 102 provided on the base plate 17, the arm 13 having the magnetic haed 12 at one end via the shafts 103 and 104 is mounted on it with rotaitonal free, and the rotor 121 of the electromagnetic operator 120 is provided at one end of the arm 111 corresponding to the stator 122. The arm tying the shafts 101 to 104 moves as dotted lines while keeping the shape of parallelogram and it can suppress the yoke angle smaller when the magnetic head 12 is moved on the desired recording track 18, and disadvantages by conventional methods can almost be avoided.
