この発明は、磁気ディスク及び磁気ヘッドが収納されて
いる構造体に酸素が存在しないようにした磁気ディスク
装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic disk device in which oxygen is not present in a structure in which a magnetic disk and a magnetic head are housed.

In the figure, (1) is a magnetic disk, (2) is a magnetic head, and (3) is a base. (4) is a cover that constitutes a sealed structure together with the base (3). (5) is a press filter, and (6) is a hole made in the cover (4) through which air flows in and out of the structure.
従来の磁気ディスク装置は以上のように構成されている
ので、磁気ディスク（１）、磁気ヘッド（２）カ収納さ
れている構造体の中は空気が入っており。Since the conventional magnetic disk drive is constructed as described above, air is trapped inside the structure housing the magnetic disk (1) and magnetic head (2).
酸素の影響で構造体の中の部品が錆びることがあるとい
う問題点があり、また、空気は窒素より重いため円板回
転時の風損が大きく１円板回転に大電流を必要とする問
題点があった。There is a problem that parts inside the structure may rust due to the influence of oxygen, and since air is heavier than nitrogen, there is a problem that windage loss when rotating the disk is large and a large current is required to rotate one disk. There was a point.
この発明は上記のような問題点を解消するためになされ
たもので１部品を錆びから防ぎ９円板回転時の風損を小
さくできる磁気ディスク装置を得ることを目的とする。The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a magnetic disk device that can prevent one component from rusting and reduce windage loss when nine discs rotate.
この発明に係る磁気ディスク装置は、プレスフィルタ（
５）、空気流通用の穴（６）をなくすとともに。The magnetic disk device according to the present invention includes a press filter (
5), along with eliminating the hole (6) for air circulation.
密閉構造体の中に、脱酸素剤を設けたものである。An oxygen scavenger is provided inside the sealed structure.
この発明における脱酸素剤は、密閉構造といっても磁気
ディスク装置の寿命までの長い期間において多少侵入し
てくる空気の中の酸素を吸収する役割を持つ。Although the oxygen absorber in this invention has a sealed structure, it has the role of absorbing some oxygen from the air that enters during a long period of time until the life of the magnetic disk device.

In the figure, (1) is a magnetic disk, (2) is a magnetic head, (3) is a haptic disk, and (4) is a cover, and unlike conventional press filters and holes for air circulation are not provided. Oa
is an oxygen scavenger provided within a closed structure.
以上のように、この発明によれば、磁気ディスク、磁気
ヘッドを収納する構造体の中に窒素を封入し、さらに脱
酸素剤を設けた構造にしたので。As described above, according to the present invention, nitrogen is sealed in the structure that houses the magnetic disk and the magnetic head, and an oxygen scavenger is further provided.
構造体の中の部品を錆びから防ぎ、また１円板回転時の
風損を小さくできる効果がある。It has the effect of preventing parts in the structure from rusting and reducing windage loss during one rotation of the disc.
