アウトの原因となる。<Prior Art> Floppy disks, which have recently attracted attention as storage elements in various information processing devices, are disk-shaped planar disks made of flexible substrates such as polyester films coated with magnetic paint. The magnetic recording medium is housed within a protective jacket. Therefore, in a completed floppy disk, the magnetic recording medium is sufficiently protected by a protective jacket, but the planar magnetic recording medium before it was made into a floppy disk did not have such protection. , dirt or dust may adhere to the surface, moisture may enter, interlayer blocking of the magnetic recording medium may cause discoloration or peeling of the magnetic film, or when a large number of sheets are stacked, vibration during transportation may cause the magnetic recording medium to discolor or peel. As a result, interlayer cracks and the like occur, resulting in dropouts.

Because of this, the number of magnetic disk veneers that can be stacked and stored in one packaging box is small, which reduces the efficiency of transport and transportation, and requires a large number of cushioning materials depending on the number of stacked disks. There are disadvantages such as a large number of parts, increased weight, and troublesome lamination work.

滑な平面に仕上げる。 When stacking the magnetic recording media 3, spacers 4 and 5 are placed on the bottom plate 101 of the case bottom plate member 1, and a large number of magnetic recording media 3 are placed thereon, with the shaft 103 inserted through the center hole 301. Stack them one after another. The number of stacked magnetic recording media 3 depends on the height H 1 of the shaft 103 and the height H 2 of the case lid member 2.
Under normal conditions, approximately 1,000 to 10,000 sheets is appropriate. After placing the spacer 6 on the stack of magnetic recording media 3, the case lid member 2 is attached.
A package as shown in FIG. 2 is obtained. In order to prevent surface irregularities from being transferred to the magnetic recording medium 3, the spacers 4, 5, and 6 have at least one surface facing the magnetic recording medium 3 made into a sufficiently smooth plane.

The edge of the opening 201 is the bottom plate 1 of the case bottom member 1.
01, the receiving portion 203 receives the tip of the shaft 103 of the case bottom member 1, and due to the springiness of the ceiling surface 202 including the bent portion 204, the entire stack of magnetic recording media 3 is attached to the case bottom member 1. It is combined with the case bottom member 1 so as to be pressed in the direction of the bottom plate 101 of the case 1.

た包装体が得られる。 As mentioned above, in the present invention, since a large number of magnetic recording media 3 are directly stacked and housed in the case bottom member 1 and the case lid member 2, the number of stacked magnetic recording media can be reduced to 1000. It is possible to produce a very large number of sheets, up to about 10,000 sheets, and a package suitable for mass packaging can be obtained.

で、運搬時等に磁性層が損傷を受けることがな
い。このような保護作用は、主として、次の働き
によつて得られる。 The magnetic recording medium 3 has a base made of polyester film and is flexible, and a magnetic layer that is easily damaged is provided on the surface of the base.
Although it is difficult to handle and requires extreme care to avoid scratches, magnetic recording media 3
Since the entire laminate is protected by the cases 1 and 2, the magnetic layer will not be damaged during transportation or the like. Such a protective effect is obtained mainly through the following functions.
まず、磁気記録媒体３の中心孔３０１に軸１０
３を挿通させて磁気記録媒体３の多数枚を積層す
る構造であるから、多数枚の磁気記録媒体３が、
軸１０３によつて横ズレを防止されながら確実に
積層される。 First, the shaft 10 is inserted into the center hole 301 of the magnetic recording medium 3.
Since the structure is such that a large number of magnetic recording media 3 are stacked by inserting the magnetic recording media 3 into
The shaft 103 prevents lateral displacement and ensures reliable stacking.
しかも、屈曲部２０４を含む天井面２０２のバ
ネ性により、磁気記録媒体３の積層体の全体が、
ケース底部材１の底面板１０１の方向、つまり上
下方向に、適度の圧力で押し付けられる。 Moreover, due to the springiness of the ceiling surface 202 including the bent portion 204, the entire stacked body of the magnetic recording medium 3 is
It is pressed in the direction of the bottom plate 101 of the case bottom member 1, that is, in the vertical direction, with an appropriate pressure.
このため、運搬時等に振動が発生しても、磁気
記録媒体３が相互に動くことが殆どなく、層間摩
擦による磁性層表面の損傷、それによるドロツプ
アウトの発生等が確実に防止できる。 Therefore, even if vibrations occur during transportation, the magnetic recording media 3 hardly move relative to each other, and damage to the surface of the magnetic layer due to interlayer friction and the occurrence of dropouts due to this can be reliably prevented.
更に、磁気記録媒体３の積層体の最下層及び最

ツプアウトの問題を生じる。 As the arrangement position of the spacer, the magnetic recording medium 3-
A structure in which the spacer is placed between the magnetic recording media 3 and 3 is also considered, but in this case, the amount of stacked magnetic recording media 3 is reduced, and the planar shape of the spacer is transferred to the magnetic recording medium 3 between the magnetic recording media 3 and 3. This causes dropout problems.

減少する。 On the other hand, if the magnetic recording media 3 are stacked directly and the spacers 4, 5, and 6 are arranged on both sides, unlike the case where the spacers are interposed between the magnetic recording media 3, The amount of accumulated magnetic recording media 3 can be doubled, and
Transfer of the shape of the spacer during the stacking of the magnetic recording medium 3 does not occur, and the probability of dropout occurrence is significantly reduced.
上述のようにして、多数枚の磁気記録媒体３を

る。 After stacking and storing a large number of magnetic recording media 3 in the cases 1 and 2 as described above, as shown in FIG. Vacuum pack in step 7 to obtain the finished product. This air suction force during vacuum packaging generates a pressing force that presses the stack of magnetic recording media 3 against the cases 1 and 2, making it possible to more reliably prevent movement of the magnetic recording media 3 within the cases 1 and 2. Damage to the surface of the magnetic layer due to interlayer friction, occurrence of dropouts, etc. can be more effectively prevented. Furthermore, vacuum packaging has the excellent advantage that the pressing force against the stack of magnetic recording media 3 can be adjusted by adjusting the air suction force.

できる。 Since the surface of the magnetic film of the magnetic recording medium 3 is mirror-finished, if moisture intrudes into the cases 1 and 2 and condensation occurs, the magnetic film surface is likely to discolor and the magnetic film peels off due to interlayer blocking. In the present invention, the entire case 1, 2 containing the stacked body of the magnetic recording medium 3 is covered with a packaging film 7.
Cases 1 and 2 are vacuum packed by
Dirt, dust, or moisture will not enter the inside of the case 1 or 2 from the outside, and no dew condensation will occur inside the cases 1 and 2. Therefore, discoloration of the surface of the magnetic film and peeling of the magnetic film due to interlayer blocking can be prevented.
