引き起こす危険性が高かつた。 Conventionally, it has been very difficult to make a flexible magnetic recording medium into a thin cartridge because the rotation of the flexible magnetic recording medium becomes unstable. For example, as shown in FIG. 1, if the distance between the stabilizing plate 1 and the auxiliary plate 2 of the cartridge is widened (10 mm to 20 mm or more) and the flexible magnetic recording body 3 is interposed therebetween, it will be relatively A stable rotational state can be obtained, but the cartridge is large. 4 is a rotational drive motor, and 5 is a magnetic head. Also, the second
As shown in FIG. 3, a stabilizing plate 6 and an auxiliary plate 8 having a plurality of holes 7 are used, and by opening the periphery, the distance between the stabilizing plate 6 and the auxiliary plate 8 can be adjusted using a spacer 9.
There is a device that allows the flexible recording medium 3 to rotate stably by eliminating the influence of the auxiliary plate 8 by narrowing the auxiliary plate 8. There was a high risk that impurities and the like would enter and cause performance problems such as dropouts.
そこで、本発明はこのような問題を改善したカ

４図以下に示す実施例を参照して詳細に説明す

磁気ヘツドである。 In the figure, reference numeral 11 denotes a flexible magnetic recording body, whose central portion is easily reinforced and held by rings 12 and 13. Reference numeral 14 denotes a stabilizing plate, which together with the ring 12 forms a manifold 15 of an air inflow section. An auxiliary plate 16 has a magnetic head movement hole 17 and forms a manifold 18 with the ring 13. Reference numeral 19 denotes a spacer that aligns the magnetic head moving hole 1 with respect to the rotation center of the flexible magnetic recording body 11.
An open portion 20 is formed in the same direction as 7. The shape of this spacer 19 does not necessarily have to be a circular portion 21 on the inside as shown in FIG. 4, and may be linear as shown in FIG. 6 without any problem. Further, 22 is a filter provided in the open portion 20, and 23 is a magnetic head.

めに著しい損傷が生じる。 When the flexible magnetic recording body 11 is rotated by the motor 24, air flows from the manifolds 15 and 18 to the flexible magnetic recording body 11, the stabilizing plate 14, and the auxiliary plate 16.
flows between. When the open part 20 is sealed like the other outer peripheral parts, the inflowing air has only the magnetic head movement hole 17 as an outflow part, and the flexible magnetic recording body 11 is attracted to the magnetic head movement hole 17, increasing vibration. Significant damage may occur due to contact with the auxiliary plate 16 and rotation.

置する方向以外を開放した場合も、磁気ヘツド２

At position 3, only the magnetic head movement hole 17 serves as an air outlet, and the entire outer periphery is in a sealed state.

安定なものにし得た。 On the other hand, if the outer periphery in the same direction as the position of the magnetic head 23 is opened as shown in the figure, the velocity component of the air in the circumferential direction is large.
A much larger amount of flow flows out from the filter 22 of the opening 20 than that flowing out from the opening 7, and the influence of the magnetic head movement hole 17 can be reduced. Therefore, vibrations are also reduced and stable rotation can be obtained.
Therefore, the life of the flexible magnetic recording body 11 can be extended. According to experiments, using this configuration, the gap between the stabilizing plate 14 and the auxiliary plate 16 was narrowed to just over 1 nm, and the flexible magnetic recording body 11 could be rotated without coming into contact with the stabilizing plate 14 or the auxiliary plate 16. This made it possible to stabilize the contact between the flexible magnetic recording body 11 and the magnetic head 23.

できる。 The above is a case of the upper contact method (a method in which the magnetic surface of the flexible magnetic recording body 11 is on the opposite surface to the stabilizing plate 14, and the magnetic head 23 contacts from the magnetic surface side). As shown in the figure, even in the case of the lowering method (a method in which the magnetic surface of the flexible magnetic recording body 11 faces the stabilizing plate 14 and the magnetic head 23 comes into contact with the stabilizing plate 14 from the side), at least the magnetic By opening the outer circumference of the cartridge in the same direction as the head movement hole 17, a much larger amount of flow flows out from the open part 20 than from the magnetic head movement hole 17, and comes into contact with the stabilizing plate 14 and the auxiliary plate 16. The flexible magnetic recording body 11 can be rotated stably without any trouble.

撓性磁気記録体１１の挙動に変化は生じない。 In addition, a filter 22 with good ventilation is provided in the open part 20.
By providing this, it is possible to suppress the inflow of impurities from the outside. Even if this filter is provided, no change occurs in the behavior of the flexible magnetic recording body 11.

ものである。 As described above, according to the present invention, it is possible to make the cartridge thin regardless of the method, and stable rotation of the flexible magnetic recording body is obtained, thereby improving the life span. Also, the cartridge becomes thinner,
In addition, since the outer circumference of the cartridge is almost sealed,
It is possible to obtain a flexible magnetic recording medium in which damage to the flexible magnetic recording medium and contamination of impurities during handling are reduced.
