Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic head support device that performs magnetic recording and reproduction on both sides of a flexible magnetic disk.

FIG. 1 shows the configuration of a conventional magnetic head support device. A flexible magnetic disk (hereinafter referred to as a magnetic disk) 1 is inserted into an envelope-shaped jack (not shown) and rotated by a VC mounted on a spindle (not shown).

The flexible magnetic disk 1 is supported by two sliders 2, and information is recorded and reproduced using a core (not shown) and a winding (not shown) K built into the slider 2.

The slider 2 is a thin metal plate (for example, 0.1) 5Fa)
When the gimbal flexure 4 (hereinafter referred to as F gimbal) is touched by hand such as M, stable surface contact is made with the magnetic disk 1 by the action of the gimbal 40. It has 17 degrees of freedom (11 degrees of freedom in 6 directions).

Furthermore, the force is also received by the load spring 6,
”) maintains the surface contact pressure constant.

The gimbal 4 is positioned via a spacer 5 by an arm 6 (rigid body) K according to a predetermined gluing method.3. The two sliders 2 each use a slider with a small force as a pad 1-, Achieves stable surface contact and ensures good recording and playback durability. If either Mochizui or Monote7rari becomes unstable due to the influence of one or the other, the same phenomenon will occur with the curved horse.

The basic operating principle of the conventional structure described above is that the two sliders follow the change in height in the surface direction of the magnetic disk 1 due to deformation.

However, in reality, due to variations in the force of the load lug 9, undulations due to distortion when the magnetic disk 1 is mounted on the spindle, and variations in the set height, the height difference between the slider 2 and the magnetic disk 10111 is quite large. , There were some cases that could not be covered by just one cut of the slider 2 (-shot +7iJ), and as a result, it was not possible to obtain normal recording and playback characteristics.

The object of the present invention is to eliminate the problems of the prior art as described above, and to completely eliminate variations in parts and work.

The feature of this invention is that the magnetic deflection has a free direction in no direction, and the surface direction is) 1 ((direction or
While holding one free cut in a fixed direction, the height of the surface direction with respect to the disk surface is fixed at the optimum height, and the height of the latter slider is actually set magnetically. This is to make the disc warp.

Next, embodiments of the present invention will be explained in detail using the drawings.

It has directional freedom.

Furthermore, the height of the 1G magnetic disk 1 is fixed by the flange 7 attached to the arm 6.
