本発明は密封型磁気デイスク装置に係り、特に
記録媒体としてスパツタ等の連続媒体を使用する
場に好適な密封型磁気デイスク装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sealed magnetic disk device, and particularly to a sealed magnetic disk device suitable for use in a continuous medium such as a sputter as a recording medium.

The conventional technology uses a sealed container 1 as shown in FIG.
A moisture absorbent case 2 having a connection hole 6 and a breathing hole 9 is attached to a part of the container, and a moisture absorbent 4 is sealed in the case 2 to dehumidify the inside of the sealed container 1.

In the above conventional technology, only the flow path structure between the inside of the sealed container and the inside of the case containing the moisture absorbent has been devised, and if left as is, the rate of diffusion of humid air would be too fast and the inside of the sealed container would be too fast. There was a problem that the humidity could not be maintained for a long period of time.

When the outside air passes through the moisture absorbent and the flow path in the case and is guided into the sealed container, a partition plate with a throttle inside the case serves as a passage resistance against the diffusion and intrusion of moisture. Generally, a moisture absorbent has the property that the larger the humidity difference, the faster the water absorption rate, and the shorter the life span. Therefore, by partitioning the room with a plurality of plates having aperture holes, a humidity difference occurs between each partitioned room. Therefore, when the moisture absorbent in the room close to the outside air approaches saturation, the moisture absorbent in the next inner room comes into play, so even if the same amount of moisture absorbent is used, it is not possible to partition the room in this way. This has a significant retarding effect when considering the environmental lifespan of its final room humidity limits.

れている。 Connecting holes 6 are provided at the corners of the front sealed container 1 to allow air to enter and exit depending on changes in environmental conditions, and a filter 5 is attached to the inside of the sealed container to prevent dust from outside air from entering. . Further, a moisture absorbent enclosing case 2 is arranged on the outer surface of the corner portion of the sealed container 1. The case 2 is provided with a breathing hole 9 and a connecting hole 6, and its interior is partitioned into three chambers by a partition plate 3 having throttle holes 7 and 8. Also, 3
A moisture absorbent 4 is sealed in a case 2 partitioned into chambers.

長される効果がある。 Next, the operation of this embodiment will be explained. Inside the magnetic disk device, air flows in and out of the device due to heat generated by the motor, etc., but a dust filter is attached to the breathing hole to keep the inside of the device clean. This breathing air may contain a large amount of moisture.
Highly humid outside air passes through the breathing hole 9 of the case 2 and enters the first chamber 1.
3 and is dehumidified by the moisture absorbent 4. 1st room 13
When the moisture absorbent inside absorbs enough moisture and reaches its water absorption limit,
Moisture in the outside air enters the second chamber 15 through the breathing hole 9 and the throttle hole 8, and is dehumidified by the moisture absorbent 4 in the second chamber 14. The moisture absorbent 4 in the second chamber 14 is in the first chamber 1.
As in the case of 3, when the water absorption limit is reached, the moisture in the outside air passes through the breathing hole 9 and the throttle holes 8 and 7 and enters the third chamber 15.
At the same time, it enters the sealed container 1 in which the disk is stored. The humidity inside the sealed container is approximately equal to the humidity in the third chamber, as shown in FIG. 3.
The vertical axis is relative humidity, and the horizontal axis is environmental lifespan. When the inside of case 2 is divided into three rooms using the same amount of moisture absorbent,
When the critical humidity is set to 70%, the environmental lifespan is 5 years, which is 2 years longer than the conventional single room case shown in Figure 4.

れる効果がある。 Furthermore, if the structure is sealed except for the breathing hole, as in the case of a magnetic disk device, when low-humidity internal air is exhausted through the desiccant case, the moisture in the desiccant will be expelled to the outside and reactivated. Therefore, there is an effect that is actually expected to be longer than the effect shown in FIG. 3.
本発明によれば、磁気デイスク装置内は同量の

効果がある。
According to the present invention, even if the same amount of moisture absorbent is used in the magnetic disk device, it is effective to maintain a lower humidity state for a longer period of time than in the past.
