Description

Description: TECHNICAL FIELD The present invention relates to a mounting structure of a storage device mounted on a system.

[Conventional technology]

2. Description of the Related Art In recent years, as systems such as information processing devices have become more portable, small-sized storage devices mounted thereon, such as floppy disk devices (FDD) and fixed disk devices (HDD), have been significantly reduced in size and size.

Generally, these FDDs and HDDs are firmly screwed at the four corners to the system from the viewpoint of reliability and stability of operation.

[Problems to be solved by the invention]

However, if these storage devices are firmly fixed at the four corners as in the above-mentioned conventional case, the storage devices are totally distorted (twisted) at the time of installation or severe use after mounting the system due to their delicate structure. However, there is a disadvantage that so-called off-track easily occurs.

Accordingly, an object of the present invention is to provide a practical and practical storage device mounting structure capable of minimizing off-track, although there is no particular difference in terms of fixing.

[Means for solving the problem]

In order to solve the above problem, the present invention relates to a storage device mounting structure for mounting and fixing a storage device to a system, wherein one of two portions on both sides of a substantially central stroke of a moving head of the storage device is provided. Is fixedly fastened to the system and the other portion is pressed against the system by pressing means so as to be mounted so as to be displaceable minutely.

(Operation)

One of the two locations on both sides of the approximate center of the stroke of the head is fastened and attached, and the other is attached with a universal joint so that the small storage device can be attached and fixed. Even when external force acts during use, the four corners are not firmly fixed, so it is difficult for excessive force to be applied.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of a small storage device according to an embodiment of the present invention, and FIG. 2 is a front view of the small storage device of FIG.

Referring to these drawings, reference numeral 1 denotes a small storage device such as an FDD or an HDD, which includes a disk 2 for recording information, a head 3 for accessing information, and a driving mechanism 4 for driving the head 3. And has a box-shaped appearance.

The storage device 1 has an extremely delicate frame structure, such as a bent aluminum plate material, in order to reduce the size and weight. Also, the storage device 1 is controlled only by the feed accuracy of a lead screw (not shown in detail) without servo control. Since a system for assuring the position of the head 3 is employed, its mounting structure poses a major problem.

Hereinafter, a characteristic portion of the present embodiment that solves this problem will be described. The storage device 1 is attached to the base 20 of the system via the L-shaped mounting members 6a and 6b on both sides thereof. This will be described in more detail.
The moving head 3 is fixed to the base 20 at two locations on both sides of the approximate center of the stroke. That is,
On the other hand, on the left side, the mounting member 6a is
On the other (right) side, the mounting member 6b has a conical projection 11 of the pressing member 10 screwed to the base 20.
The storage device 1 is fixed to the base 20 in such a manner that the storage device 1 is pressed toward the base side in a universal joint type.

Therefore, when the storage device 1 is mounted and fixed to the system, unnecessary force is hardly applied to the storage device 1, and even if an external force that bends (or twists) the entire system is used when the system is used, the above two mounting portions are not attached. The shape and the like can be easily held at the center like a seesaw. Therefore, a great effect can be expected in terms of reliability and stability such as suppression of off-track.

Here, the effect of the present embodiment confirmed experimentally is shown in FIG. This is shown by measuring track deviation in the head portion when various steps are provided at any of the four corners of the apparatus. With the conventional structure, the track deviation is extremely large as shown in (b), but according to the mounting structure of this embodiment (a), the track deviation is small as a whole, that is, when the apparatus is mounted or after mounting. This means that the distortion of the apparatus itself is small even when the system is used. That is, off-track can be suppressed to a minimum, and the reliability of the system is improved.

The pressing member is inserted into the through hole for the mounting screw of the mounting member 6b.
Instead of pressing the ten conical protrusions 11 so as to insert them, a recess may be provided in the mounting member 6b and the recess may be pressed one point (pivot type) from above.

〔The invention's effect〕

As described above, according to the present invention, the storage device is supported at two locations with a boundary where off-track occurs,
One part is fastened and fixed, and the other part is pressed by the pressing means and attached so that it can be displaced minutely, so that an external force is less likely to act on the main body of the storage device, so that off-track can be minimized and the reliability of the system can be reduced. Etc. are improved.
