會用い、それに取り例は穴２金設けた構造をしている。As shown in FIG. 1, a conventional disk-shaped recording medium has a structure in which a hole 2 is provided in the center of a circular 82-shaped journal medium 1. Alternatively, in order to reinforce the hole, the decoy may have a separate structure 3 such as a core bar in the center of the disc-shaped recording medium 1, as shown in FIG.
For general use, it has a structure with two holes.

、高さのすｎを逃げることができる。As shown in Figure 3, the height of the disk extraction e-recording medium drive circuit axis 4 (hereinafter referred to as the light axis) of the recording device, and the values of p and f'L written as all four pieces of data written on the recording medium. When the height of the head 5 for reading and erasing the female data is large enough, if the disk 8@e recording medium 1 is sufficiently malleable, the disk 8@e recording medium 1 has the same height as shown in FIG. The plate-shaped recording medium flexes and can escape the height.
しかしながら、円板状ＭＥ’録媒体１の可撓性が十分で

以下実施例に基づいて本発明の詳細な説明する。The invention is to eliminate such drawbacks, and its purpose is to provide sufficient deformability to the disk-shaped IE' recording medium and completely prevent damage to the head and the disk-shaped recording medium. Based on the following examples. The present invention will now be described in detail.

If the rotation 14 and the height of the head 5 are different, the disc-shaped WF
Since the recording medium 1 has a gimbal-shaped deformation area 7,
It can be easily transformed into the shape shown in FIG.

用いると六わめて有効である。Therefore, by reducing the height, the head and disk-shaped recording medium can be protected from damage. J: Historical record area 6, deformation area 7, and excavation area 8 are the same material. The deformation region 7 can be created by forming a gimbal shape at the same time as the hole 2 is created, and can be manufactured very easily. This embodiment is extremely effective when used in cases where the disc-shaped recording medium has some flexibility but is not sufficiently flexible.

い。FIG. 6 1d shows another embodiment according to the present invention, in which numeral 6 is a recording area, 9 is a deformation area made of an elastic material, and 8 is a portion that is connected to the rotating shaft. Since the disc-shaped recording medium has a deformable region made of an elastic material, it is easily deformed as in the above embodiment, and protects the head and the disc-shaped recording medium from total damage. This example is
It is preferable to use this method when the disc-shaped recording medium has low OJ flexibility.

It's a minute. The deformation region 10 is a gimbaled elastic material. In this case, the deformation area 10 may be a harder hole η than the deformation area 9 of the above-mentioned embodiment, and in this example, the additional phrase is the part 8
The same material is used. The disc-shaped recording medium according to this embodiment is also easily deformed as in the previous embodiment, and protects the head and the disc-shaped @e recording medium from damage. Note that the shape of the deformation region is not limited to the gimbal shape, and may be any other shape, such as a bellows shape.

止にすぐｆ′した効果を有するものである。The invention is achieved by providing a deformable region in a disc-shaped recording medium.
This is to give sufficient deformability to the disc-shaped recording medium and to prevent a large amount of force from being generated at the contact area between the head and the disc-shaped recording medium. This has an immediate effect in preventing damage to the C recording medium.
