is a screw, 9F is Jimba Hell, 9G is a magnetic head,
9H is the servo head, 91゛ is the bearing, 9D
9-1 is a rotating shaft, 9-1 is an arm assembly, and 11 is a spindle mechanism.

Claims (1)

[Scope of utility model registration request] A magnetic head that performs recording and reproduction, a rotating shaft that rotates,
A swing arm having a through hole inserted into the rotation shaft and to which the magnetic head is fixed, and a plurality of swing arms are stacked and clamped so that the through holes are concentric with each other to form an arm. The arm assembly and the rotation shaft are fixed at a predetermined position by forming an assembly and inserting the rotation shaft into the through hole, and the rotation of the rotation shaft is performed through the arm assembly. In the actuator mechanism for moving the magnetic head, the axial diameter of the rotating shaft is formed by a large diameter portion fitted into the through hole and a small diameter portion having a gap, and The small diameter portion is an actuator mechanism characterized by being provided at a predetermined pitch.
