[Purpose of the invention]

0002

[Field of Industrial Application] The present invention relates to a magnetic disk device in which a magnetic disk as a magnetic recording medium is fixed to a rotatable spindle, and more specifically, the present invention relates to a magnetic disk device in which a magnetic disk as a magnetic recording medium is fixed to a rotatable spindle. This relates to an attachment mechanism for attaching to.

2. Description of the Related Art A magnetic disk device is known in which a magnetic disk serving as a magnetic recording medium is fixed to a rotatable spindle and rotationally driven by a motor.

As shown in FIGS. 7 and 8, a conventional magnetic disk drive 101 has screw holes 10 on the side and bottom of the housing.
3 and 105 are provided, and support plates 109 and 111 of host devices such as computers are provided with tapping screws 107 and the like.
It can be attached to a host device by screwing it to the

[0005] With such an attachment method, it is often difficult to attach or remove the magnetic disk drive, so the magnetic disk drive is generally used while attached to a host device.

On the other hand, as a result of the remarkable progress in miniaturization of magnetic disk drives, magnetic disk drives have come to be of a size that allows them to be carried around. Accordingly, it is desirable to make the magnetic disk device itself portable so that large amounts of data can be easily moved.

[0007]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a mounting mechanism that allows a magnetic disk device to be easily inserted into and removed from a host device such as a computer.
To enable a magnetic disk device to be used in a portable and replaceable form.

[Structure of the invention]

[0009]

[Means for Solving the Problems] In the mounting mechanism of the present invention, a guide rail is fixed to a host device such as a computer, and a supporting means that is slidable along the guide rail is fixed to a magnetic disk device. It is characterized by:

0010

[Operation] The engagement between the guide rail and the slidable support means allows the magnetic disk device to be easily inserted into and removed from the host device.

Embodiments Hereinafter, embodiments of the present invention will be explained based on the drawings. In different drawings, common components are designated by the same reference numerals and redundant description will be omitted.

FIGS. 1 and 2 show a first embodiment of the present invention, in which a magnetic disk drive 1 includes a disk drive head assembly 3 and a circuit board 5. FIG. Disk drive head assembly 3 has a housing 7. Although not shown, the housing 7 includes a disk drive assembly in which a magnetic disk as a magnetic recording medium is fixed to a spindle and rotated by a motor, and a magnetic head for recording and reproducing is attached to the disk surface. A head assembly is housed therein for movement along. The circuit board 5 also includes a spindle motor control circuit and a carriage drive control circuit for controlling the disk drive head assembly 3, and a recording data control circuit for driving a magnetic head to record and reproduce data. An interface control circuit (none of which is shown) for connection with a host device is fixed. The housing 7 and the circuit board 5 are connected via a bush 9.

A pair of parallel channel-shaped guide rails 13 are fixed to the housing 11 of the host device using screw holes 15 and tapping screws 17. On the other hand, the circuit board 5
A pair of parallel elongated support members 19 are screwed to both ends of the guide rail 13, and these support members slide along the guide grooves of the guide rail 13.

With such a configuration, the support member 19
By moving the magnetic disk device 1 relative to the housing 11 of the host device while engaging the guide grooves of the guide rails 13, the magnetic disk device 1 can be easily inserted into and taken out from the host device.

FIG. 3 shows a second embodiment of the invention. In the first embodiment, the support member 19 was fixed to the circuit board 5, but in this embodiment, the support member 21 is integrally formed with the housing 7 of the magnetic disk drive 1. The other configurations are the same as in the first embodiment.

FIG. 4 shows a third embodiment of the present invention.
In this embodiment, a space in which no circuit components are mounted is secured on the circuit board 5 along both edges 23 in the longitudinal direction of the circuit board 5, and both edges 23 of the circuit board are directly connected to the guide rails 13. The magnetic disk device 1 can be moved in and out of the host device by matching the two.

FIG. 5 shows a fourth embodiment of the present invention.
Disk drive head assembly 3 and circuit board 5
A magnetic disk drive 1 consisting of the following is fixed to a frame 25, and a support member 27 that engages with the guide rail 13 is fixed to this frame 25. Therefore, the magnetic disk device 1 and the frame 25 as a whole can be taken in and out of the host device, and can also be moved and replaced.

FIG. 6 shows a fifth embodiment of the invention. In this embodiment, the guide rail 29 is made of an angle-shaped member, and a longitudinal groove 33 is formed in the side surface of the frame 31. By engaging the groove 33 of the frame with the guide rail 29 and sliding the entire magnetic disk device 1 and frame 31,
The magnetic disk device 1 and the frame 31 can be taken out and replaced as a whole.

[0019]

As can be seen from the above, according to the present invention, a magnetic disk device can be easily replaced in the same way as a conventional magnetic disk cartridge. It becomes possible to carry, share, and store magnetic disk devices.
