Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information storage device that can be attached to and detached from a device body (so-called detachable type), and more particularly to an information storage device having excellent mechanical strength.

[0002]

2. Description of the Related Art Hard disk drive devices (hereinafter referred to as H
This will be described as DD. ) Plays an important role as a recording / reproducing apparatus for writing data and programs and reading recorded data in information processing apparatuses such as personal computers.

This HDD can be attached to and detached from not only the main body of the information processing apparatus but also the main body of the information processing apparatus.
It is also being considered for use as a small information storage device which is a so-called detachable type medium. Such an information storage device is detached from the information processing device main body as necessary, and is carried by itself or stored separately from the information processing device main body. Furthermore, it is used by being attached to a portable device.

By the way, conventional HDDs are generally of the open type, in which the atmospheric pressure in the information storage device also changes in response to changes in the atmospheric pressure of the surroundings. Specifically, a hole called a breathing hole is formed in the top cover of the HDD, and even when the external pressure of the information storage device changes, the HDD
It is designed so that the atmospheric pressure inside the housing that accommodates is the same as the external atmospheric pressure.

[0005]

However, in the above-mentioned open type HDD, there are cases where the reading and writing of data is hindered by the external atmospheric pressure. In an HDD, when reading and writing data to and from a hard disk, the magnetic head is floated from about 10 to several tens of nm above the surface of the disk. However, it is difficult to maintain the flying height of the magnetic head in a normal state according to the change in atmospheric pressure, which may hinder the reading and writing of data and the like. For example, since the atmospheric pressure is low in high altitudes such as Mt. Fuji, the Alps and Everest, the flying height of the magnetic head may be lower than that in the flat ground, and the magnetic head may come into contact with the surface of the hard disk. In the case of the HDD, the HDD may be carried in various places such as a recording medium for a camera, and the above problem is remarkable.

Therefore, a structure in which the flying height of the magnetic head is normally maintained by sealing the housing in which the HDD main body is housed can be considered, but stress is applied to the housing due to the atmospheric pressure difference between the inside and outside of the housing. The case may be deformed. For example, when the HDD main body housed in a case hermetically sealed in a high altitude of 5000 m is carried, the external atmospheric pressure drops to about 0.5 atmospheric pressure. Then, the internal pressure (1at
m) and the atmospheric pressure (0.5 atm) (0.5 a)
tm) is generated as pressure inside the housing, and the housing swells. In such a situation, the information storage device inserted in the information processing device may become physically large and may damage the information processing device. Further, even if the information storage device is not damaged, the information storage device cannot be taken out from the information processing device.

Further, the volume of air inside the casing increases due to the expansion of the casing, and the internal pressure inside the casing decreases, making it difficult to maintain the internal pressure inside the casing at 1 atm.
Therefore, there is a demand for a structure in which the housing is hermetically sealed, the mechanical strength of the housing is increased so that the volume of air inside the housing is not increased, and the housing is not easily deformed.

Therefore, the present invention has been made in view of the above problems, and an object thereof is to provide a detachable type information storage device in which the mechanical strength of a casing having an improved hermeticity is greatly improved. And

Further, as in this example, the reinforcing plate 46 has a shape in which the hollow portion 48 is formed in a part thereof, but the hollow portion 48 may not be formed. The reinforcing plate 46 is formed separately from the lower half portion 90 in advance, and is arranged on the bottom portion 47 so as to be integrated with the lower half portion 90 to improve the mechanical strength of the lower half portion 90. When attaching the reinforcing plate 46 to the bottom portion 47, the reinforcing plate 46 and the bottom portion 47 may be bonded to each other with a double-sided adhesive tape, or a hole may be formed in a part of the reinforcing plate 46 to form the bottom portion 47. The bottom portion 47 and the reinforcing plate 46 can be joined by crimping the head portion of the pin after inserting the pin into this hole. In this example, the stage portion 49 formed in the arrangement region 44 is replaced with the hollow portion 48 formed in the reinforcing plate 46.
The reinforcing plate 46 is fixed to the lower half portion 90 by fitting the reinforcing plate 46 and the arrangement area 44 together.

The peripheral edge of the reinforcing plate 46 has a substantially rectangular shape, and is smaller than the size of the bottom portion 47 forming the lower half portion 90. The material forming the reinforcing plate 46 has higher rigidity than the material forming the lower half portion 90. For example, when the lower half portion 90 is formed of an organic polymer material such as plastic, aluminum or the like is used. A metal material can be used. Therefore, the reinforcing plate 46
By integrating the lower half portion 90 with the lower half portion 90, without forming the entire lower half portion 90 with a material having high rigidity,
The mechanical strength of the upper half portion 90 can be increased. In particular, since aluminum is relatively lightweight, the weight of the lower half portion 90 is not significantly increased.
Further, the material forming the reinforcing plate 46 is not limited to a metal material, and may be a composite material such as a fiber reinforced plastic in which glass is mixed with an organic polymer material. In addition, the reinforcing plate 46
