Abstract

PURPOSE: To prevent an inner space of a magnetooptical disk device from being contaminated by corrosive gas by a simple means. CONSTITUTION: A container 9 including a gas adsorbent 8 is freely detachably mounted in the outside of the plate 5 of a magnetooptical disk device. The gas adsorbent 8 in the container 9 is circulated in an inner space 7 included by the plate 5 and a cover 6 through a filter 11 provided in the through hole 10 of the palte 5 and a filter 13 provided in the through hole 12 of the container 9. Corrosive gas generated from the inner parts of the magnetooptical disk device or corrosive gas entered from the outside into the inner space 7 is adsorbed by the gas adsorbent 8 in the container 9 through the filters 11, 13.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magneto-optical disk device, and more particularly to a cleaning mechanism for the internal space of the device.

[0002]

2. Description of the Related Art Conventionally, in a magneto-optical disk device, a single magneto-optical disk for recording / reproducing information is limited in order to increase the storage capacity. The storage capacity above is increasing. Details of the above configuration will be described with reference to the drawings. FIG. 2 shows an example of a conventional magneto-optical disk device.

In the drawing, a magneto-optical disk 2 is contained in a cartridge 3. The magneto-optical disk 2 is rotated by a spindle motor 4. The optical head 1 optically writes / reads information on / from the magneto-optical disk 2. When the cartridge 3 and the magneto-optical disk 2 are replaced, the cover 6 is opened and taken out from the magneto-optical disk device to be replaced. Normally, the cover 6 is closed, and the spindle motor 4, the optical head 1, the cartridge 3, and the magneto-optical disk 2 are covered by the cover 6.
The plate 5 has a hermetically sealed structure that protects the optical head 1 from dust. Since the cover 6 is normally closed, the internal space 7 contained therein tends to be in a sealed environment for a long time.

It is noted that installing a gas adsorbent for removing harmful organic gas, a gas absorbent and a moisture absorbent, or a desiccant inside a magnetic disk device is disclosed in JP-A-60-2196.
95, JP-A 1-211296, or JP-A 4-247386.

[0005]

In the above-described conventional magneto-optical disk device, since the internal space is a sealed environment, a corrosive gas is generated in the internal space or a corrosive gas is externally supplied. However, there is a disadvantage that the internal space is contaminated with corrosive gas for a long time and the internal parts of the magneto-optical disk device are corroded.

Therefore, the present invention aims to improve the above-mentioned drawbacks of the conventional magneto-optical disk device and to prevent the internal space of the magneto-optical disk device from being contaminated by corrosive gas by a simple means. is there.

[0007]

To solve the above problems, the present invention provides a magneto-optical disk for storing information, a cartridge containing the magneto-optical disk, and a magneto-optical disk when the cartridge is mounted. A spindle motor for rotating the optical disc, an optical head for optically writing and reading information on the magneto-optical disk,
In a magneto-optical disk device having a plate and a cover that encloses the spindle motor, the optical head, the magneto-optical disk, and the cartridge, a gas adsorbent capable of adsorbing a corrosive gas is included outside the plate. A purifying mechanism of a magneto-optical disk device in which a container is mounted, a filter is provided in a through hole opened in the container, and a filter is provided in a through hole opened in the plate is adopted as a means.

[0008]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a sectional view of a magneto-optical disk device showing an embodiment of the present invention as seen from the front.

In the drawing, the magneto-optical disk 2 is contained in a cartridge 3. The magneto-optical disk 2 is rotated by a spindle motor 4. The optical head 1 optically writes / reads information on / from the magneto-optical disk 2. When the cartridge 3 and the magneto-optical disk 2 are replaced, the cover 6 is opened and taken out from the magneto-optical disk device to be replaced. Normally, the cover 6 is closed, and the spindle motor 4, the optical head 1, the cartridge 3, and the magneto-optical disk 2 are enclosed by the cover 6 and the plate 5 to form a hermetic structure that protects the optical head 1 from dust. Has become. A container 9 containing a gas adsorbent 8 is attached to the outside of the plate 5.
The inner space 7 enclosed in the cover 6 and the plate 5 is provided with a filter 11 provided in the through hole 10 opened in the plate 5 and a filter 13 provided in the through hole 12 opened in the container 9. , And is in communication with the gas adsorbent 8 contained in the container 9.

The corrosive gas generated from the internal parts of the magneto-optical disk device or the corrosive gas that has entered the internal space 7 from the outside is the gas adsorbent 8 contained in the container 9 through the filters 11 and 13. Is adsorbed on. Since the container 9 containing the gas adsorbent 8 is provided outside the plate 5, the container 9 containing the gas adsorbent 8 sufficiently adsorbs the corrosive gas and becomes saturated and loses its adsorption ability. The whole container 9 can be easily replaced, and the gas adsorbent 8 having an adsorbing capacity can always be provided. It should be noted that it is more convenient if the filter 11 is attached to the plate 5 and the filter 13 is attached to the container 9 so that they can be detached and replaced individually.

[0011]

As described above, according to the present invention, a detachable container containing a gas adsorbent is attached to a magneto-optical disk device, and the internal space is contaminated with corrosive gas by a simple means. It is possible to prevent corrosion of internal components and PKG due to corrosive gas, improve the durability of the components of the magneto-optical disk device, and improve the reliability of the magneto-optical disk device.
