に、シリカゲル等の乾燥剤４が取り付けられている。Detailed Description of the Invention [Industrial Field of Application] The present invention relates to a magnetic disk package and a packing method, and particularly to prevention of dust adhesion to magnetic disks during unpacking and dew condensation caused by rapid changes in the outside air environment. This article relates to a magnetic disk package and packaging method that solves the problem. [Prior Art] Magnetic disks in which a ferromagnetic metal thin film is formed on a nonmagnetic substrate have been put into practical use as high-density recording media. Magnetic disks are generally produced by forming a ferromagnetic metal thin film magnetic layer on a non-magnetic metal substrate such as an aluminum alloy or a disc-shaped substrate with a non-magnetic metal layer such as nickel provided thereon by electroless plating, sputtering, etc. Manufactured. Conventionally, manufactured magnetic disks are packaged and shipped as shown in FIG. 2 using a caddy 10 shown in FIG. 3. This conventional packaging method will be explained below. FIG. 2 is a cross-sectional view showing a conventional packing method, and FIG. 3 is an internal perspective view showing a general caddy 1o of the type that holds a magnetic disk horizontally (horizontally). The caddy IO shown in FIG. 3 has a bottom portion 1 having a core rod 11 erected on a central axis for inserting and holding a magnetic disk through its spindle insertion hole.
2. A substantially truncated conical cover 13 placed on the bottom 12, a cap 14 for fixing the cover 13 to the bottom 12, an upper packing 3, and a contact portion between the cover 13 and the bottom 12. It mainly consists of a lower packing 15 for sealing. The covering part 13 has an opening formed in the center of the upper surface through which the core rod 11 is inserted, and by screwing the tip of the core rod 11 protruding from the hole and the cap 14, the covering part 13 can be opened.
and the bottom part 12 are brought into close contact with each other through the lower packing 15, thereby sealing the caddy 10. Conventionally, such a caddy 10 is used, and the spacer 2 and the magnetic disk 1 are first attached to the core rod 11 of the caddy 10.
and insert them alternately. Although not shown, after inserting the number of magnetic disks 1 accommodated in the caddy 10 (normally about 25 disks), an upper packing 3 is provided and a cover 13 is provided, and a cap 14 is attached to the cover 13. 13 is fixed to the bottom part 12 and sealed (in addition, the packing 15 is omitted from illustration in FIG. 2). Cover part 1 of this caddy 10
A desiccant 4 such as silica gel is attached to the inner surface of the caddy 3 so as to absorb moisture within the caddy 10.

、信頼性に悪影響を及ぼすものである。Caddy 10 loaded with magnetic disk 1 in this way
is further wrapped in double (or triple or more) packaging using laminated sheets 5 and 6. That is, when using the magnetic disk 1, the caddy 10 is brought into the clean room with the entire caddy 10 inside, so the caddy 10 must not be contaminated with dust. For this reason, the caddy 10 is wrapped in a laminated sheet. Since single-layer packaging is unreliable in terms of strength, it should be wrapped in two or more layers. The laminate sheets 5 and 6 used include a special polyethylene layer as an inner layer, a special polyolefin layer and a nylon layer laminated in this order, and a special polyolefin layer as an outer layer. When packaging with these laminated sheets 5 and 6, the insides of the laminated sheets 5 and 6 are heat-sealed under reduced pressure to prevent condensation from forming due to sudden changes in the outside air environment. (In Fig. 2, 5a and 6a indicate the heat-sealed parts.). Normally, the pressure inside the laminated sheet 5, which is the first packaging, is reduced to 600 mmHg.
Also, inside the laminated sheet 6, which is the second packaging, there are 4
It is said that the reduced pressure is 0.00 mmHg. [Problems to be Solved by the Invention] In the conventional packaging method described above, the packaging using the laminate sheets 5 and 6 is vacuum packaging, so the internal atmosphere returns to normal pressure when unpacking. At that time, surrounding dust may be attracted and adhered to the caddy 10 and further to the surface of the magnetic disk 1 inside the caddy 10. Further, adhering dirt and dust may come out from the desiccant 4 provided in the caddy 10, and the desiccant 4 may cause contamination of the magnetic disk 1. Such adhesion of dirt and dust adversely affects the performance and reliability of the magnetic disk.

In the magnetic disk package 20 of this embodiment, the inside of the laminate sheet 5 (i.e., SA in FIG. 1) and the inside of the caddy 10 (i.e., Sc in FIG. 1), which are the first packaging, are under normal pressure. It is said to be the nitrogen gas Reiki. Also, the desiccant 4 is in the caddy 1.
It is attached to the outer surface of the cover 13 of 0. Note that no upper packing is provided at the bottom of the cap of the caddy 10. The rest of the structure is similar to that of the conventional package shown in FIG.

気であるため、外気の変化により結露することはない。In this way, the sA inside the laminate sheet 5 is not at reduced pressure but at normal pressure, and is in a nitrogen gas atmosphere, so the upper packing of the caddy 10 (upper packing 3 in Fig. 2) is unnecessary. Ru. Furthermore, in the magnetic disk package 20 of this embodiment,
A desiccant 4 such as silica gel is attached to the outer surface of the cover 13 of the caddy rather than the inner surface.
It is possible to reliably prevent contamination. On the other hand, the SB between the laminate sheet 6 and the laminate sheet 5 for the second packaging is 400 mmH as before.
It is said that the pressure is reduced to about 1.5 g. When unpacking such a magnetic disk package 20, first, when opening the laminate sheet 6, the pressure inside the laminate sheet 6 is reduced, so there is a risk of attracting dust from the surrounding area. However, the suctioned dirt is blocked by the laminate sheet 5 and does not reach the caddy 10. When the laminate sheet 5 is opened, since the inside of the laminate sheet 5 is under normal pressure, surrounding dust will not be sucked in and the caddy 10 and the magnetic disk 1 in the caddy 10 will not be contaminated. ．． Furthermore, during transportation and storage, the pressure inside the laminate sheet 6 is reduced and the inside of the laminate sheet 5 is in a nitrogen gas atmosphere, so that dew condensation does not occur due to changes in the outside air.
このような磁気ディスク梱包体２０は、請求項（２）の

The covering part 13 is fixed to the bottom 12 with the cap 14 and sealed. In this case, the lower packing (not shown) is preferably interposed between the bottom part 12 and the covering part 13 in order to stabilize the adhesion between them, but it may be omitted. Next, after attaching the desiccant 4 to the outer surface of the cover 13 of the caddy 10, the package is first wrapped with a laminated sheet 5.
At this time, the pressure inside the laminate sheet 5 is once reduced, and N2 gas is sucked in using a nozzle. After depressurizing again, N
After repeating this depressurization and inhalation of N2 gas to sufficiently replace the inside of the laminate sheet 5 with nitrogen gas at normal pressure, it is heat-sealed (5a). During this nitrogen gas replacement, the air inside the caddy lo is also naturally replaced with nitrogen gas through the gap in the cap 14 portion.
