本発明は、ハードディスクやフロッピィディスク等の磁
気記録媒体を収納するための磁気記録媒体用収納器に関
する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic recording medium storage container for storing magnetic recording media such as hard disks and floppy disks.
かかる磁気記録媒体用収納器において、従来では、磁気
記録媒体を収納する収納ケースが紙やプラスチ・7り等
で作成されていた。In such a magnetic recording medium storage device, the storage case for storing the magnetic recording medium has conventionally been made of paper, plastic, paper, or the like.
上記従来構成の収納ケースでは、磁力線に対するシール
ド機能を有していないため、収納ケースが外部からの強
い磁力線にさらされたとき、この収納ケース内の磁気記
録媒体に記録されている磁化の向きが反転したり、消去
されてしまう可能性があった。The storage case with the conventional configuration described above does not have a shielding function against magnetic lines of force, so when the storage case is exposed to strong magnetic lines of force from the outside, the direction of magnetization recorded on the magnetic recording medium inside the storage case will change. There was a possibility that it would be reversed or erased.
本発明の目的は、近年になって非常に注目され始めた新
しい物質を有効利用することによって、磁気記録媒体の
保存が外部磁界の影響を受けることなく良好に行えるよ
うにする点にある。An object of the present invention is to enable magnetic recording media to be stored effectively without being affected by external magnetic fields by effectively utilizing a new substance that has recently begun to attract much attention.
本発明の特徴構成は、磁気記録媒体を収納する収納ケー
スの全域に渡って、超電導体から成る磁気遮蔽層を形成
した点にある。A characteristic feature of the present invention is that a magnetic shielding layer made of a superconductor is formed over the entire area of a storage case that stores a magnetic recording medium.
すなわち、外部からの強い磁力線が収納ケースに向けて
発せられると、この磁力線とは反対方向の磁力線が超電
導体から発生し、これら両磁力線同士が相殺されるマイ
スナー効果によって、外部からの磁力線が収納ケース内
に侵入することを阻止するのである。In other words, when strong lines of magnetic force from the outside are emitted toward the storage case, lines of magnetic force in the opposite direction to the lines of magnetic force are generated from the superconductor, and due to the Meissner effect in which these two lines of magnetic force cancel each other out, the lines of magnetic force from the outside are accommodated. This prevents them from entering the case.
したがって、収納ケースの全域に渡って超電導体で成る

えるようになった。Therefore, by forming a magnetic shielding layer made of superconductor over the entire area of the storage case, strong lines of magnetic force from the outside can be completely blocked, and the direction of magnetization recorded on the magnetic recording medium can be reversed. The magnetic recording medium can now be stored satisfactorily for a long period of time without being erased or erased.

の磁力線を発生するように構成してある。FIG. 1 shows a storage case (2) that houses a hard disk (1) as a magnetic recording medium used in a fixed magnetic disk device. As shown in FIG. 2, a magnetic shielding layer (3) made by coating a powdered superconductor is formed on the entire outer surface of the storage case (2), so that lines of magnetic force from outside are prevented from entering the storage case (2). 2) It is configured to generate lines of magnetic force in a direction repelling the lines of magnetic force so that they do not enter the inside of the magnetic field.
尚、前記超電導体を構成する材料によっては、超電導状

ス(2)を構成して実施してもよい。In the above embodiment, the magnetic shielding layer (3) is placed in the storage case (2).
Although it is formed on the outer surface of the storage case (2), it may be formed on the inner surface of the storage case (2), or the storage case (2) may be constructed of the magnetic shielding layer (3) itself.
