）やオーディオテープレコータヤコンピュータに用いる
磁気テープなどを保管する磁気記録媒体保管ケースに関
するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to video tape recorders (hereinafter abbreviated as VTR) and audio tape recorders that record and reproduce video and audio information signals on magnetic tape, magnetic tapes used in computers, etc. This relates to a magnetic recording media storage case for storing.

欠点があった。Problems to be Solved by the Invention However, the material of the VTR tape storage case described above is ineffective against magnetism. This has the disadvantage that noise may be mixed into or erased from already recorded video and audio signals.
本発明は上記問題点に鑑み、ＶＴＲテープ保管用ケース

のである。In view of the above problems, the present invention provides a magnetic recording medium storage case that has no effect on recorded video and audio even under strong magnetic field conditions by making the VTR tape storage case using a superconducting material that has a magnetic shielding function. This is what we provide.

映像信号と音声信号を保持し、再生することができる。Function The present invention uses a superconducting material to form a magnetic recording medium storage case, thereby preventing a strong magnetic field from approaching the case due to the Meissner effect of the superconducting material.
Beautiful video and audio signals can be maintained and played forever without affecting the already recorded signals.
実施例

れて保管するのである。Therefore, we created a VTR tape storage case 5 made of superconducting material such as yttrium, barium, copper, etc., which can house the case 1, and use the VTR tape storage case 5 when the VTR deck is not recording or playing. 6 and store it.
その保管状態を第１図中に点線で示す。Its storage condition is shown by the dotted line in FIG.
尚、第１図に示した実施例は、ＶＴＲテープの例を示し
