Abstract

PURPOSE:To make the structure difficult to generate the deformation of a gimbal and to stabilize the quality as well by fixing the outer periphery of the gimbal fixed with a magnetic head to a fitting part and arranging the step part or projecting part regulating the turning operation of the gimbal to the inner part of this fixing part. CONSTITUTION:A step part B is provided at the square recessed part A of the gimbal fixing part of a slider 12. Namely due to the outer periphery of the gimbal 13 to which a magnetic head 9 is fixed being fixed to the step part B of a square recessed part A the turning of the gimbal 13 is regulated by the step part B, which may be formed as a projection part. The gimbal 13 is thus regulated by the step part or projection part at its turning, so the strength against the deformation of the gimbal is increased and it becomes strong against the deformation and stabilized on the quality as well.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a magnetic disk recording/reproducing device used in various office automation equipment.

BACKGROUND OF THE INVENTION In recent years, magnetic disk recording/reproducing devices have been rapidly progressing in use as random access memories that are easy to handle, highly reliable, and inexpensive, and are increasingly being applied to electronic devices, personal computers, and the like.

Part 6 about conventional general magnetic disk recording and reproducing devices
This will be explained using figures.

FIG. 6 is a perspective view showing the inside of a conventional magnetic disk recording/reproducing device, in which the magnetic disk 1 for recording and reproducing information is
Magnetic disk cartridge 2 that rotatably supports this
3I cam plate 4 and stopper 5
The data is sent to the recording/playback position of the main body of the apparatus by a loading device equipped with the following.

The rotation drive device 6 rotates the magnetic disk 1.

It is driven by an electric motor 8 via a belt 7.

The magnetic head 9 disposed so as to be in contact with the surface of the magnetic disk 1 is driven in the radial direction of the magnetic disk 10 by the magnetic head transport device 1°.

A control circuit section 11 that controls the movements of the magnetic disk rotation drive device 6 and the magnetic head feeding device 10 described above, as well as the recording and reproducing of the magnetic disk 1 by the magnetic head 9, is mounted on the bottom of the main body of the device.

The operation of the magnetic disk recording/reproducing apparatus configured as above will be explained.

First, the magnetic disk cartridge 2 is attached to the recording/reproducing position of the main body of the apparatus by a loading device, and at the same time the magnetic disk 1 is rotated by the magnetic disk rotation drive device e, the magnetic head feeding device 10 is activated to generate a magnetic disk. The head 9 is moved in the radial direction and remains stationary at a predetermined relative position for recording on or extracting recording from the magnetic disk 1.

Next, an electric signal from the control circuit section 11 causes the magnetic head 9 to
Information is recorded on or reproduced from the magnetic disk 1 through the magnetic disk 1.

FIG. 4 (IL), (+)) shows the structure of a magnetic head 9, a gimbal, and a slider of a conventional magnetic disk recording/reproducing device.

The outer periphery of a rotatable gimbal 13 with an integrated magnetic head 9 is fixed to the upper surface of the recess of the slider 12 having a rectangular recess with an adhesive.

Problems to be Solved by the Invention However, in the head fixing method using the above structure, since the gimbal 13 is rotatable, problems such as those shown in FIGS.
Since there is no limit to the rotational movement of the gimbal 13, there is a high possibility that the gimbal 13 will be deformed, and if this problem occurs, it cannot be corrected.

The present invention has been made in view of the problems of the prior art, and it is an object of the present invention to provide a magnetic disk recording/reproducing device which has a structure in which deformation of the gimbal is unlikely to occur and is stable in terms of quality. be.

Means for Solving the Problems In order to achieve the above object, the magnetic disk recording/reproducing apparatus of the present invention has the following features:
A stepped portion 1 is fixed to the mounting portion and is located inside the fixed portion to restrict rotational movement of the gimbal. Or it is one in which protrusions are arranged.

With this configuration, the rotation of the gimbal is restricted by the step or protrusion, so it is resistant to deformation and stable in terms of quality.

The overall structure of the magnetic disk recording and reproducing apparatus according to the embodiment is as follows.
It is substantially the same as that shown in the drawings, and only the features of the present invention will be described below with reference to the drawings.

1, 2(a), 3(b), and 3 show an embodiment of the present invention.

The figure shows a case where a stepped portion B is provided in the rectangular recessed portion of the gimbal fixing portion of the slider 12, and the outer periphery of the gimbal 13 to which the magnetic head 9 is fixed is fixed to the stepped portion B of the rectangular recessed portion. . Therefore, rotation of the gimbal 13 is restricted by the stepped portion B.

Note that the stepped portion B may be a protrusion.

Effects of the Invention As described above, since the magnetic disk recording/reproducing device of the present invention restricts the rotation of the gimbal with the stepped portion or the protrusion, the strength against deformation of the gimbal is increased.

The quality is also stable.
