会も増大している。[Detailed description of the invention] Recently, various types of magnetic recording media such as cash cards, magnetic tapes, and floppy disks have become widely used, but due to the increasing use of various health care devices that apply magnetism, There is also an increased chance that data stored in magnetic recording bodies will be damaged by the proximity of these instruments.
従つて磁気記録体を外部の強力な磁界から保護

アイルの製造では薄鉄板を所定の大きさに切断す
る作業とこの使用が含まれる。 Accordingly, various magnetic recording storage files having a magnetic shielding function to protect magnetic recording media from external strong magnetic fields have been proposed and are commercially available. In principle, this type of file has a ferromagnetic material sheet such as a thin iron plate built into the front and back covers to obtain a magnetic shielding effect. However, the manufacture of this type of file involves cutting and using thin iron sheets to size.
本考案は薄鉄板を使用せず、この代りに鉄粉又

業と低コストで磁気記録体を安全に保護する保存
フアイルを提供しようとするものである。 The present invention does not use a thin iron plate, but instead uses an adhesive mixed with a high ratio of iron powder or highly magnetic material powder such as permalloy, thereby creating a magnetic recording medium with simple work and low cost. It aims to provide storage files that are securely protected.
以下本考案の好適実施例を示す添付図面によつ
て説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, the front cover 1 and back cover 2 of the file of the present invention have a soft foam or cardboard 3 with a thickness of about 3 mm in the center, and papers 5 and 5 on both sides of the file.
The entire body is wrapped in a synthetic resin sheet 6. The above-mentioned soft foam or center cardboard 3 is 3 mm thick to obtain a magnetic field attenuation effect proportional to the square of the distance.
It is preferable to have a thickness greater than or equal to this.
In the illustrated embodiment, the front cover 1 and the back cover 2 are integrally connected by a narrow connecting part 8, and a plurality of magnetic recording material storage bags 7 are fixed to this connecting part 8.

できる。 As mentioned above, the magnetic recording storage file of the present invention does not use two thin iron plates in the front and back covers, but uses a high-content iron powder adhesive to wrap the front and back covers in one piece. Since everything except the resin sheet can be made of paper, it can be manufactured easily and inexpensively, and the magnetic recording medium can be shielded from strong external magnetic fields to prevent damage to the magnetic recording and safely protect it.
