Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a disk cartridge containing a disk-shaped recording medium such as an optical disk, a magnetic disk, and a magneto-optical disk.

[0002]

2. Description of the Related Art Conventionally, disks such as optical disks, magnetic disks, and magneto-optical disks have been used as disk-shaped recording media. These discs are sometimes used by being enclosed in a disc cartridge in order to prevent recording / reproducing errors due to dust or the like adhering to the recording surface. In particular, most of the discs on which the user performs recording work Is usually contained in a cartridge in most cases.

[0003] By the way, if the disk-shaped recording medium has the same recording density, a disk having a larger diameter naturally has a larger recording capacity. On the other hand, when the above-described disc-shaped recording medium is used as a recording medium for a portable recording / reproducing apparatus, for example, a video camera, a small disc is more excellent in portability. For this reason, disks of different sizes may be used as disks of a portable device and disks of a stationary device capable of supporting a large capacity. At this time, a small disk cartridge used for the portable disk is naturally used for convenience. When the recording method is the same and only the shape of the disc is different, if the disc can be mounted on the recording / reproducing device, recording / reproducing can be performed by the recording / reproducing means provided in the recording / reproducing device, that is, disc compatibility is possible. become. For this reason, only the disk is taken out from the small disk cartridge and replaced with a disk cartridge having the same outer shape as the disk cartridge of the stationary device, thereby recording / reproducing the small disk used in the portable device by the stationary recording / reproducing device. It becomes possible to do.

As a structure for taking out a disk from a disk cartridge, for example, there is a method of disposing a disk insertable / removable part in a part of the disk cartridge as shown in Japanese Patent Laid-Open No. Hei 5-242626.

[0005]

FIG. 8 shows a disk insertion / removal structure of a conventional disk cartridge. Shutter 3d
The disk insertion / removal opening 12c is provided on the side opposite to the side where is disposed, and the disk insertion / removal opening / closing member 8d is disposed there. Normally, the locking claw 9 of the disk insertion / removal opening / closing member 8d is fitted to the disk cartridge, and the disk insertion / removal opening 12c is closed by the disk insertion / removal opening / closing member 8d. When removing the disk 4, the locking claw 9 is removed, the disk insertion / removal opening / closing member 8d is rotated about the fulcrum 28, the disk insertion / removal opening 12c is opened, and the disk 4 is inserted / removed. in this case,
The user takes out the disk 4 directly by hand.

As a means for moving a disk without directly touching the disk, a moving method for moving the disk via a disk holder has been proposed. In this method, a disk cartridge is composed of a main body part and a disk holder, and when moving the disk, the disk holder is held on the disk,
Since the disk is moved together with the disk holder, it does not directly touch the disk.

Incidentally, recently, DVD-ROM / RAM
Disks that are used as signal surfaces on both sides are becoming widespread. In the case of such a disk, it is particularly difficult to set the printing surface on the disk, so the user can later determine the information about the disk, that is, what data file name, software name, manager, date, etc. are included. It becomes difficult.

Further, when a disk is moved between different cartridges, in the conventional method, only the disk is moved, and the information provided on the disk cartridge does not move. Further, even when a disk holder is used, the movement of information of the disk cartridge is not considered.

Furthermore, the disk and / or disk holder do not have an area in which the user can later write or rewrite information, for example, the name of a file or software written on the disk.

According to the present invention, information which can be arbitrarily written by a user is written in a label area of a disk holder as a disk holding member, and when the disk is moved between different cartridges, the disk and the disk holder can be moved together. It becomes.

[0011]

In order to solve the above-mentioned problems, a disk holder is arranged in a small disk cartridge. The disk holder has a removable structure, and the disk can be removed from the disk cartridge body together with the disk holder.

Further, the disc holder is provided with a label area where a user can write or erase necessary information arbitrarily and / or an area where a label is attached. In other words, information that can be written and / or erased by the user as needed with respect to the disk is provided in the disk holder, and even if the disk cartridge changes,
Disc information is left in the disc holder.

This is because, for example, the same disc is housed in a different disc cartridge body and used depending on the recording and / or reproducing apparatus, and when the disc is moved between different disc cartridges, the disc is moved via a disc holder. This indicates that the disc holder and the disc contents correspond even when the disc is moved to a different disc cartridge in order to move the disc.

The label area and / or the area to which the label is to be attached are set in advance so that even if a paper label or the like is attached to the disc holder, the label area and / or the area to which the label is attached do not rise on the surface on which the area is provided. It is configured to have a recess of 2 mm or more.
