点で荷重を加えられている。A conventional magnetic head slider support mechanism is called a Watrous type and includes a load spring that applies a predetermined load to the magnetic head slider and a gimbal spring that fixes the magnetic head slider. FIG. 2 is a perspective view showing such a conventional magnetic head slider support mechanism. In FIG. 2, the surface of the magnetic head slider 1 opposite to the air bearing surfaces 2a and 2b is fixed to a gimbal spring 11, and this gimbal spring 11 is fixed to a load spring 21. This magnetic head slider support mechanism has a load spring 2.
1, the load set by gimbal spring 11
The magnetic head slider 1 is attached to the magnetic head slider 1 through an embossing 12 provided on the magnetic head slider 1. That is, the magnetic head slider 1 is placed on the surface opposite to the air bearing surfaces 2a and 2b.
A load is applied at a point.

るという欠点がある。The conventional magnetic head slider support mechanism described above has a structure in which a load can be applied to the magnetic head slider at one point on the surface opposite to the air bearing surface, so the load is applied to the center of gravity of the magnetic head slider and the magnetic head slider. does not match the point of adding . Therefore, when acceleration is applied during seek, a moment is generated, the magnetic head slider is tilted, and the flying heights of the two air bearing surfaces become different on the left and right sides. recent years,
The acceleration during lick seek to shorten access time is increasing, and therefore there is a high risk of one of the two air bearing surfaces coming into contact with the magnetic disk medium, a so-called head crash, and the reliability of magnetic disk drives is decreasing. The disadvantage is that it decreases.

れるようにしたことを特徴とする。The present invention provides a floating magnetic head slider for writing and reading information to and from a magnetic disk medium, a gimbal spring for holding the magnetic head slider, a gimbal spring fixed to one end, and a load applied to the magnetic head slider. The magnetic head slider support mechanism is characterized in that the magnetic head slider has a recess in the air bearing surface and is held in the recess by a gimbal spring.
次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

リング１１と接着されている。FIG. 1 is a perspective view showing an embodiment of the present invention. A gimbal spring 11 is welded and fixed to a load spring 21 made of a thin plate of stainless steel or the like. The gimbal spring 11 is made by pressing, cutting, etc. a single plate such as a thin plate of stainless steel. The embossing 12 is formed on the gimbal spring 11 by a press working method. The magnetic head slider 1 is bonded to a gimbal spring 11 at a recess 3 sandwiched between left and right air bearing surfaces 2a and 2b.

The center of gravity of the magnetic head slider 1 and the point at which a load is applied to the magnetic head slider 1 can be aligned by setting the distance between the air bearing surfaces 2a, 2b and the recess 3 to a predetermined dimension. can.

上量が異なることはない。Here, the moment generated by the acceleration during seek is the center of gravity of the magnetic head slider l and the moment of the magnetic head slider l.
Since it is proportional to the distance from the point to which the load is applied, if the two match as in this example, the generated moment will be zero, and the flying height of the left and right flying surfaces 2a and 2b will be different during seek. There isn't.

果がある。As explained above, in the magnetic head slider support mechanism of the present invention, since the magnetic head slider is held by the recessed cymbal spring formed on the air bearing surface of the magnetic head slider, the center of gravity of the magnetic head slider and the magnetic head slider are The point at which the load is applied can be made to coincide with the point at which the load is applied. Therefore, since the magnetic head slider support mechanism of the present invention does not generate a moment due to acceleration during seek, the magnetic head slider and the disk do not come into contact during seek, and a highly reliable magnetic disk device can be obtained. be.
