Abstract

PURPOSE:To eliminate the displacement of a mount, and to attain recording with high density, by fixing one of plural head mounts on which a magnetic head is fixed, in the radius direction of a pivot axis, and pressing the other mounts with a spring. CONSTITUTION:Head mounts 12, 13, and 14 are fixed at a pivot hub 11 by piercing through a screw 16, and two springs 15 are tightened on the mount 13, and other two mounts 12 and 14 are pressed with the spring 15. Therefore, since no looseness, or displacement between the mounts, or between the mount and the hub, is generated even when an external force is applied on them, off-track is reduced, thereby, it is possible to realize the recording with high density.

The head mount A12, head mount B13, and head mount C14 are assembled with screws 16 and attached to the pivot hub 1. Further, it is fixed from the side with screws 17. Further, a spring 15 is used between the head mount and the screw 17. These springs firmly press head mounts A, B, and C from the sides. FIG. 2 is a sectional view showing this. This allows head mounts A, B, and C.
