Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an optical disk cartridge.

[0002]

2. Description of the Related Art An optical information recording disk has an advantage over a magnetic disk or the like in that recording / reproduction is not affected even if some dust or dust is present on the surface thereof, however, the surface dirt, When dust, fingerprints, etc. are remarkable, it is natural that a servo error occurs and normal recording / reproduction is hindered. Although a disk-dedicated cleaner has been proposed in order to solve the above-mentioned drawbacks, it imposes a heavy burden on a user who has to purchase a cleaner.

As shown in FIG. 4, in many cases, the so-called cartridge 11 is contained in the disk drive for the purpose of protecting the disk 13 from dust, dirt, and scratches. For recording / reproduction, the surface of the disc must be exposed and dust or dirt may adhere to the surface of the disc during long-term use, which may interfere with recording / reproduction. In such a case, the surface of the disc needs to be cleaned, but the disc 13 is taken out from the cartridge 11, or the shutter 12 of the cartridge 11 is opened to use a paper, cloth, or the like on the disc surface.
It is necessary to wipe the dirt by hand. Such an operation can achieve its purpose if done carefully, but if the material used to wipe the dirt is wrong, it often causes scratches that cannot be recorded / reproduced on the disk surface. In order to avoid such a situation and to facilitate maintenance of the optical information recording disk, a disk cleaning dedicated machine has been proposed, but this also makes it difficult for the user to purchase the cleaning machine and complicate the operation. Considering this, the purpose is insufficient.

[0004]

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an optical disk cartridge capable of reducing recording / reproduction troubles caused by dust or dirt on the disk surface.

[0005]

In order to achieve the above object, the present invention provides (1)
In an optical disc cartridge having a structure in which an optical disc is put in a case, a means for wiping dirt off the disc surface is provided on the surface of the cartridge, or
(2) In an optical disk cartridge having a structure in which an optical disk is put in a case, a means for wiping dirt off the surface of the disk is attached to the surface of the cartridge, and further, (3) in (1) or (2) above, In the above (1) or (2), the means for wiping off the dirt is formed by soaking a cloth or paper with a liquid suitable for wiping off the dirt, and storing the cloth or paper in a bag in which the cloth or paper is in close contact. ,
The cloth or paper, which is a means for wiping off the dirt, is characterized by being a material that can be regenerated when the dirt is washed off. Hereinafter, description will be given based on examples of the present invention.

FIG. 1 is a block diagram for explaining an embodiment of an optical disk cartridge according to the present invention. In the figure, 1 is a cartridge, 2 is a shutter, 3 is a disk, 4 is a lid for storage, and 5 is a wipe. It is a member. According to the present invention, a dedicated paper or cloth 5 for wiping off dirt is stored in the cartridge 1 without damaging the surface of the disk 3. Alternatively, it is configured to be attached to the surface of the cartridge 1. In FIG. 1, a pull-out type pocket is provided on the surface of the cartridge 1, and the wiping member 5 is housed in the pocket. To remove the wiping member 5,
The lid 4 for storage is opened and closed by sliding in the direction of the arrow in the figure.

FIG. 2 is a view showing another embodiment of the optical disk cartridge according to the present invention. In FIG. 2, 6 is a bag in which a wiping member is sealed, and other parts having the same functions as those in FIG. I am doing it. The wiping member 5 is housed in a sealed bag 6, and the bag is attached to the surface of the cartridge 1.
When the wiping member 5 is taken out, the sealed state of the upper end portion of the sealing bag 6 can be released and taken out.

The cartridge of FIG. 2 does not have a large thickness, but has a pocket structure, whereas the cartridge of FIG. 3 has a thicker cartridge due to the provision of the bag. In actual use,
As shown in FIG. 3, it is desirable to remove the bag 6 from the cartridge 1 before use. If the bag 6 is still attached to the cartridge 1, it may cause a trouble of being caught in the drive. As described above, the present invention is a cartridge to which a disc and a cleaning-dedicated material are added. Therefore, the effect of significantly reducing the risk of damaging the surface of the disc such that recording and reproduction cannot be performed can be expected. The material of the wiping member is pencil hardness, B to 2H.
There is no restriction as long as it is a material that can wipe off dirt without damaging the substrate of, but cotton or bencott (made by Asahi Kasei) is preferable, and synthetic fibers such as polyester and rayon should not be damaged, and the sealed bag should be If you soak a solvent such as ethanol or IPA (isopropyl alcohol), the dirt will come off even better. The bag may be a bag made of copolyethylene or the like, and preferably has a velcro tape that can be sealed.

[0009]

As is apparent from the above description, according to the present invention, since the surface of the optical disk cartridge is provided with the means for wiping off the dirt on the disk surface, the recording / reproducing trouble due to the dirt or dirt on the disk surface can be easily reduced. can do.
