Abstract

PURPOSE:To obtain the supporting structure of a magnetic head slider capable of high density packaging by holding the two head sliders with respective beam materials, fitting the base edge side of the beam materials to one plate and fitting the plate to the one side of an actuator arm. CONSTITUTION:The base edge 2f of two pieces of beam materials 2 to hold a magnetic head slider 1 is fixed on both the bop and under faces of the tip top side of a plate 3 by spot welding at plural points shown by a code 2a. The base edge 3f of the plate 3 is fixed by a fitting screw 5 screwed to a tapped hole 7 of an actuator arm 4 through a hole 3m. Accordingly, the one plate 3 is enough to be fitted to the one side of the actuator arm 4, and moreover, the thickness of the actuator arm 5 to be fitted with a pc. of fitting screw 5 is enough. Then, the space of a magnetic disk 6 can be made small and high density packaging is attained. Thus, the supporting, structure of the magnetic head slider to make the high density packaging of a magnetic disk device easy can be obtained.

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a support structure for a core slider for holding a magnetic head that writes and reads data, and in particular, it relates to a support structure for a core slider for holding a magnetic head that writes and reads data, and particularly relates to a support structure for supporting a core slider for holding a magnetic head that writes and reads data. This relates to what is attached to the actuator arm.

[Conventional technology]

As a prior art support structure for a core slider for holding a magnetic head, there is one shown in FIGS. 4 and 5. In the figure, 1 is a core slider that holds a magnetic nod 1a;
2 is a beam material, and 3 is a plate.

The beam material 2 is made of an elastic plate material, and presses the core slider 1 attached to the tip end thereof against the magnetic disk 6 with a constant force. Further, a plate 3 provided at the other end of the beam material 2 is made of a rigid plate material, and is fixed to the actuator arm 4 by a mounting screw 5. In magnetic disk drives, the plates 3 are often mounted on both the front and back sides of the actuator arm 4, and the upper and lower two plates 3 are screwed into the screw holes 7 of the actuator arm 4 through the holes 3a of the plate 3. It is fixed by the mounting screw 5 that is inserted. Thereby, two core sliders 1.1 are attached to one actuator arm 4.

[Problem to be solved by the invention]

As described above, the support structure of the conventional core slider for holding the magnetic head requires two upper and lower plates, making the overall thickness within the thickness, and the actuator arm 4 also needs to be thick enough for the mounting screw 5 to be attached from above and below. However, there was a problem in that the stacking interval of the magnetic disks 6 could not be narrowed.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a support structure for a magnetic head holding core slider that can be mounted at high density.

[Means to solve the problem]

In the support structure of a core slider for holding a magnetic head according to the present invention, two beam members are attached to two plates, and the plate 3 is fixed to an actuator arm.

[Effect]

Core slider l that holds the magnetic head in this invention
contacts the opposing surface of the magnetic disk with a constant pressure. Further, one plate is attached to the actuator arm.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Note that the same parts as in FIGS. 4 and 5 are designated by the same reference numerals. 1 and 2 are perspective views showing one embodiment of the present invention, and FIG. 2 is an overall external appearance when it is incorporated into a magnetic disk device.

The support structure of the magnetic head holding core slider of the embodiment is as follows:
The base ends 2f of the two beam members 2 holding the magnetic head holding core slider 1 are fixed to the upper and lower surfaces of the tip side of the plate 3 by small screws 2a.

The base end 3f of the plate 3 has a hole 3m, and this hole 3m
The core slider 1 is fixed by a mounting screw 5 which is screwed into the screw hole 7 of the actuator arm 4 through the core slider 1, and the core slider 1 is pressed with a constant force against the facing surfaces of the magnetic disks 6 facing each other. The base 10 has a built-in rotary drive source 30 such as a spindle motor.
A rotating shaft 12 that is rotationally driven by a rotary shaft 12 is provided, and a plurality of disks 6 are stacked on the outer periphery of the rotating shaft 12 at regular intervals.

Here, any one of the disks 6 is a servo disk 6a, and the others are data disks, servo signals are recorded on a plurality of tracks of the servo disk 6a, and various data are recorded on a plurality of data tracks of the data disk 6. is written.

Further, a drive shaft 14 is installed in the housing 13 provided on the base 10 so as to remain parallel to the rotation shaft 12, and an actuator arm 4 is mounted on the outer periphery of the drive shaft 14 between each magnetic disk 6. A plurality of them are provided to correspond to the following.

On the other hand, inside the housing 13, there is provided a groove drive section 31, such as a voice coil motor, which moves the slider 1 in the radial direction of the disk 6 and makes it face a predetermined track. A positioning control circuit for controlling the head driving section 31 is provided.

Next, the operation of the magnetic disk device configured as described above will be explained.

First, the positioning control circuit controls the head drive section 31,
The actuator arm 4, which is pivotally supported by a drive shaft 14 held in the housing 13, is rotated left and right by electromagnetic force, and a plate 3. is attached to the tip of the actuator arm 4. The core slider 1 attached via the beam material 2 is attached to the disk 6.
bring it to the target position.

Here, the core slider 1 writes data to the disk 6 and reads data from the disk 6.

As mentioned above, only one plate 3 is attached to one side of the actuator arm 4, and the actuator arm 4 has a sufficient thickness to accommodate one mounting screw 5. Therefore, the interval between the magnetic disks 6 can be narrowed, and high-density packaging is possible.

[Effects of the Invention] As described above, according to the present invention, one
Since the second plate 3 is attached to one side of the actuator arm, there is an effect of facilitating high-density mounting of magnetic disk devices.
