Abstract

PURPOSE:To improve air tightness and to prevent the deformation of a main body by housing plural magnetic disk media and plural magnetic heads in the main body of a container and forming the cross section of a sheet material to be U-shaped when the container is sealed by a cover with a rubber-shaped sheet in between. CONSTITUTION:A magnetic disk medium 1 is rotated at high speed in a state that the medium 1 floats on the surface of a magnetic head 2. A space to house a lot of the magnetic disk media 1 and magnetic heads 2 is formed by a cover 3 and a main body 5 with a ring-shaped rubber seal 4 in between. The cross section of a ring in the seal 4 is formed to be U-shaped with roundness in a free state. However, in order to assemble this magnetic disk device, the seal 4 and a stopper 7 are put on the main body 5 and the main body 5 is covered with the cover 3. Then, a screw 6 is fastened until it is abutted to the cover 3 or stopper 7 and stopped. Thus, the seal 4 is crushed down to an almost V-shaped form and the enough air tight characteristic can be held without deformation of the main body 5.

。In FIG. 1, a magnetic disk medium 1 floats on the surface of a magnetic head 2 and rotates at high speed. The cover 3 and the main body 5 sandwich a ring-shaped rubber seal 4 therebetween to form a space in which a large number of magnetic disk media 1 and magnetic heads 2 are accommodated. The ring of the rubber seal 4 has a rounded U-shaped cross section in its free state, unlike the ring 4 shown in the figure.

に十分な気密を保持することが出来る。To assemble this device, place the rubber seal 4 and stopper 7 on top of the two main bodies 5, cover with the cover 3, and tighten the screws 6 until the cover 3 hits the stopper 7 and stops. As a result, the sycotom seal is crushed to a shape closer to a V than that shown at 7 in the figure. Therefore, sufficient airtightness can be maintained without deforming the main body.

Also, although the cross-sectional shape is U-shaped, this is not meant in a strict sense, but is shown as a representative of a shape close to it.

〔発明の効果〕〔Effect of the invention〕

以上説明したように９本発明の磁気ディスク装置のゴム
シールにＵ字型のものを用いているので。As explained above, a U-shaped rubber seal is used for the magnetic disk device of the present invention.
