Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] The present invention relates to a structure for fixing a magnetic head support in a magnetic disk drive used in an external storage device of a computer system. Attachment of two sets of magnetic head supports consisting of a magnetic head, a gimbal, a load beam, and a spacer to the upper and lower surfaces of the arm of the apparatus. The arm side also has screw holes corresponding to the screw holes for mounting the load beam, and the upper and lower magnetic head supports use two screw holes that do not interfere with each other. It is configured to be fixed.

[Industrial applications]

The present invention relates to a fixing structure of a magnetic head support in a magnetic disk device used for an external storage device of a computer system.

[Conventional technology]

FIG. 2 is a diagram showing a conventional magnetic disk drive. In this case, a plurality of magnetic disks 2, which are recording media, are mounted on a shaft 3 which is rotationally driven by a motor in a housing 1, and a magnetic head 4 for writing or reading information to or from the magnetic disk 2 is provided. The magnetic head 4 is supported by a carriage 7 via a magnetic head support 5 and an arm 6, and the carriage 7 moves the magnetic head 4 to an arbitrary track 8 on the magnetic disk 2.
Can be positioned.

In such a magnetic disk drive, the conventional structure for fixing the magnetic head support 5 to the arm 6 includes a magnetic head 4, a gimbal 9, a load beam 10, a spacer, as shown in FIGS. 3 (a) and 3 (b). A pair of magnetic head supports 11 and the like are used to screw the load beam 10 at the root thereof to one or two places on the upper and lower surfaces of the arm 6 with a spacer 12 with screws 12 therebetween. It is common. In this case, the upper and lower load beams use the same screw hole of the arm 6 as shown in the sectional view of FIG.
The effective length of the screw 12 is less than half the thickness of the arm 6.

[Problems to be solved by the invention]

In the above-mentioned conventional structure for fixing a magnetic head support, a medium (magnetic disk) due to recent miniaturization of a magnetic disk device is used.
The length of the screw hole for fixing the load beam 10 becomes shorter because the thickness of the arm 6 becomes thinner with the reduction of the interval,
There is a problem that a sufficient fastening force cannot be obtained.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a magnetic head support fixing structure capable of improving a fixing force of a magnetic head support to an arm.

[Means for solving the problem]

In order to achieve the above object, the fixing structure of the magnetic head support of the present invention comprises two sets of magnetic head supports 5, 5 'including a magnetic head 4, a gimbal 9, a load beam 10, and a spacer 11 of a magnetic disk drive. The magnetic head support is fixed to the upper and lower surfaces of the arm 6 and the arm 6 has four or more pits 13 for screw mounting at the base of the spacer 11 and the load beam 10, and the arm 6 is also loaded. The upper and lower magnetic head supports 5, 5 'have two screw holes A, C and B, D which do not interfere with each other. It is characterized by being fixed.

[Action]

At the same time, four or more screw holes 13 are provided at the base of the spacer 11 and the load beam 10, and screw holes A to D are provided on the arm 6 side corresponding to the screw holes 13.
The upper and lower load beams 10 are fixed to the arm 6 by using two screw holes A, C and B, D which do not interfere with each other.
, The length of the screw can be made equal to the thickness of the arm 6, and a sufficiently large fixing force can be obtained as compared with the related art.

〔Example〕

1A and 1B are views showing an embodiment of the present invention, wherein FIG. 1A is a perspective view, and FIG. 1B is a sectional view taken along the line bb in FIG.

In the present embodiment, four root holes 13 for screw mounting are provided in the root portion of the load beam 10 and the spacer 11 of the magnetic head support including the magnetic head 4, the gimbal 9, the load beam 10, the spacer 11, and the like, respectively. The arm 6 is provided with four screw holes A to D corresponding to the stupid hole 13, and the head support 5 attached to the upper surface of the arm 6 is
The head support 5 ', which is fastened and fixed with the screw 12 using the two screw holes A and C of the arm 6 and is attached to the lower surface of the arm 6, is provided with the screw holes B and D of the arm 6 other than A and C. It is used and fastened and fixed with screws 12.

In this embodiment configured as described above, since the magnetic head supports mounted on the upper surface and the lower surface of the arm 6 are fixed using different screw holes, the effective length of the screw 12 is reduced by the thickness of the arm 6. And a sufficiently large fixing force can be obtained as compared with the conventional example described with reference to FIG.

[Effect of the invention]

As described above, according to the present invention, the magnetic head supports screw-fixed to the upper and lower surfaces of the arm, respectively,
By fixing the screws using different screw holes, the tightening screw can effectively use the entire thickness of the arm, and the fixing force can be improved as compared with the related art.
