Abstract

PURPOSE:To prevent the danger of contact between a screw head part and a recording medium by providing a screw through hole, which is larger than the diameter of the screw head part, at a load spring and fixing a board by screws. CONSTITUTION:A magnetic head is composed of a magnetic head slider 2, jimbal spring 3, load spring 4a, spacer 5 and screws 6. At the screw fitting part of the spring 4a, screw through holes 9 are provided to be larger than the head part diameters of the screws 6. By these screws 6, an arm is fixed to the board part of a supporting assembly. Then, the height of the screw 6 head part can be effectively lowered. Thus, even when the head is made compact and thin, there is no danger of contact between the head parts of the screws 6 and the recording medium.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to magnetic heads and, more particularly, to mounting pressure support assemblies for magnetic heads.

[Conventional technology]

Conventionally, in this type of magnetic head, as shown in FIG. 2, a magnetic head slider 2 for writing and reading information on and from a rotating recording medium 1 is brought close to the rotating recording medium 1 by means of a load spring 4b. A spacer 5 fixed to an arm 7 attached to an actuator 8 serving as a positioning mechanism is welded, and the arm 7 and the spacer 5 portion of the load spring 4b are fixed with screws 6.

[Problem to be solved by the invention]

In the conventional magnetic head described above, a plate member 5 that is fixed to an arm 6 attached to an actuator 7 is welded to the other end of the load spring 3, and the arm 6 and the plate member 5 of the load spring 3 are connected by screws 4. Fixed. Since the distance between this screw head 4 and the recording medium 1 is only the thickness of the magnetic head slider 2, the magnetic head slider 2 of the magnetic disk device is downsized and the distance between it and the recording medium 1 is narrowed.・When trying to make it thinner, screw 4
There is a risk that the head of the screw 4 will come into contact with the recording medium 1 due to the height of the head of the screw.

[Means to solve the problem]

The present invention provides a flexible body on which a magnetic head slider is mounted, the flexible body fixed to one end, a pressure spring that applies a load for bringing the magnetic head slider close to a recording medium, and a pressure spring fixed to the other end of the pressure spring. a pressure support assembly having a fixed plate; an arm joined to a positioning mechanism section to position the magnetic head slider on a predetermined track of the recording medium; In the magnetic head provided with a screw for fixing a plate portion, the screw hole portion of the screw of the pressure spring is provided with a hole larger than at least a screw head of the screw.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1(a) is a perspective view showing one embodiment of the present invention.

FIG. 1(b) is a partial front view of FIG. 1(a). In FIGS. 1(a) and 1(b), the magnetic head of the present invention includes a magnetic head slider 2.degree. gimbal spring 3. Load spring 4a.

Consisting of a spacer 5 and a screw 6, these structures are the same as those of the conventional one, but the screw through hole 9 in the screw mounting section of the load spring 4a has a diameter larger than the head diameter d of the screw 6. It is. The diameter of the screw hole for mounting the spacer 5 with the screw is Dl, which is the same as in the conventional case.

FIG. 1(C) is a sectional view taken along the line A--A in FIG. 1(b). In FIG. 1(C), the head of the screw 6 directly presses the spacer 5 to fix the magnetic head to an arm (not shown).

FIG. 3 is a sectional view showing a conventional mounting section. Here, regarding the height of the screw 6 head seen from the surface of the spacer 5,
Comparing FIG. 3 and FIG. 1(C), Ha>82. That is, the height of the screw head of the magnetic head of the present invention is lower than that of the conventional example by the thickness H1 of the load spring.

〔Effect of the invention〕

As explained above, the present invention allows the height of the screw head to be effectively lowered by providing a screw through hole larger than the diameter of the screw head in the load spring, thereby reducing the size of the magnetic disk device. Even if the fist is made thinner, the risk of contact between the screw head and the recording medium can be avoided.
