DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for removing dust, shavings,
The present invention relates to a cleaning disk for cleaning and removing other foreign matters, dew, and the like, that is, a cleaning cartridge for an optical disk or a magneto-optical disk for cleaning a disk having a disk-shaped cleaning member by bringing the disk into contact with a lens.

[0002]

2. Description of the Related Art In a conventional optical information recording / reproducing system using a laser beam, a lens cleaner for keeping various types of foreign matter attached to an optical lens clean by removing dirt with a brush protruding from one side of a disk. It has been known.

[0003]

However, since the lens cleaner of the conventional optical disk player is not contained in the cartridge, there is no need to consider the deformation of the brush. The disc has been in the cartridge for a long time, and conventional brushes cannot be used to remove dust attached to the lens due to deformation due to the nylon fiber, and the cleaning effect cannot be sufficiently satisfied. If dew adheres, there is a problem that it is impossible to cope with a phenomenon that the refraction of light changes and optical performance deteriorates. The present invention is intended to eliminate these conventional disadvantages, and effectively removes dust, foreign matter, dew, and the like adhering to a lens, and has excellent heat resistance and abrasion resistance, and is durable even as a cartridge type. It is an object of the present invention to provide a low-cost cleaning cartridge for an optical disk device which can greatly improve the performance of the optical disk device and can maintain high performance.

[0004]

According to the present invention, there is provided a cleaning cartridge for an optical disk device, comprising a rotary disk housed rotatably in a case, and a brush for contacting the objective lens on a surface facing the objective lens. The brush is composed of at least one of carbon fiber, glass fiber and aramid fiber arranged on both sides in the rotation direction of the rotating disk, and nylon fiber arranged inside the high elastic fiber. Or a hygroscopic fiber made of rayon fiber.

[0005]

When the rotating disk is rotated by mounting the cleaning cartridge for the optical disk device on the optical disk device, the brush comes into contact with the surface of the objective lens of the optical disk device, which is in a relative relationship with the rotating disk, to remove dirt, foreign matter,
Furthermore, dew can be removed, and the surface of the objective lens can be kept clean at all times. In addition, normal dust is removed by the high-elastic fibers on both sides of the brush, and dust containing dew and moisture is removed by the hygroscopic fibers inside these high-elastic fibers, so that the objective lens is efficiently cleaned. be able to. Further, since the hygroscopic fiber is sandwiched and supported by the high elasticity fibers on both sides thereof, the set of the hygroscopic fiber can be prevented even by repeated use, and the durability of the brush can be increased.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 to 3. A rotary disk 1 rotatably accommodated in a case 10 has a brush 2 contacting the objective lens on a surface facing the objective lens. in cleaning cartridge for deployment an optical disk device in which the brush 2, carbon fibers, and excellent high modulus fibers 2 ₁ of elastic recovery force consisting of at least any one of glass fiber or aramid fibers, nylon fibers or rayon fibers consists highly hygroscopic hygroscopic fibers 2 ₂ Metropolitan consisting, it is possible to eliminate the usual dust by high modulus fibers 2 _1, hygroscopic fibers 2 ₂
As a result, dust containing dew and moisture can be removed, so that the objective lens can be efficiently cleaned.

The rotary disk 1 has a center plate 5 at the center of a disk body, and a recording / reproducing area comprising tracks or pits on which optical information or signals are recorded concentrically or spirally with the center plate 5. 3. For example, display information for the purpose of cleaning, such as music, cleaning start and end indications, and other precautions for use, is formed while maintaining a constant interval. It is provided at the position of the rotating disk exposed in the window portion 6.

[0008] As shown in FIG. 4, the highly elastic fibers 2 ₁ are arranged on both sides of the rotational direction of the rotary disk 1,
Hygroscopic fibers 2 ₂ are arranged on the inner side of these high elastic fibers 2 _1, the brush 2 is, high elastic fibers 2 ₁ and hygroscopic fibers 2 ₂
Are planted in a sandwich shape. Thus, hygroscopic fibers 2 ₂ because they are supported sandwiched by high modulus fibers 2 ₁ on both sides thereof, also to prevent the sag of hygroscopic fibers 2 ₂ by repeated use of long-term storage in the case 10 Even when the brush 2 is not deformed, the durability of the brush 2 can be increased.

The rotating disk 1 is provided with a cleaning member 4 which is in contact with a magnetic head on the other surface opposite to the one surface provided with the brush 2, and is used as a cleaning cassette for a magneto-optical disk device. The lens and the magnetic head can be cleaned uniformly. In this case, the cleaning member 4 is made of a nonwoven fabric, a flocked or polished sheet, for example, chromium oxide, aluminum oxide,
A sheet coated with an abrasive composed of silicon oxide fine particles is adhered on one side of the rotating disk 1 via an adhesive tape. The cleaning member 4 can be formed, and the cleaning effect can be enhanced by applying or impregnating a cleaning liquid as needed. The cleaning member 4 is thin (0.5 mm or less) and the information is printed on the lower surface of the cleaning member. It is convenient to be able to write.

The brush 2 is formed by fixing a brush with a brush tip directed perpendicularly to the surface of the rotating disk 1 to at least a part of the rotating disk 1 in the radial direction. In this case, the hair is implanted in the direction in which it contacts the objective lens on the opposite surface.

In FIG. 1, reference numeral 7 denotes a window hole formed on the surface of the case 10 facing the magnetic head. 8 is a rotating disk storage part, 9
Is used to integrate the upper and lower cases of the case 10 with connecting screws.

[0012]

According to the present invention, dirt, foreign matter and dew on the surface of the objective lens of the optical disk drive can be removed by the brush, and the surface of the objective lens can be kept clean at all times. An optical disk device using an optical disk or a magneto-optical disk can be maintained at high performance. In addition, normal dust can be removed by the high-elastic fibers on both sides of the brush, and dust containing dew and moisture can be removed by the hygroscopic fibers inside these high-elastic fibers. The lens can be cleaned. Furthermore, since the hygroscopic fiber is sandwiched and supported by the high elasticity fibers on both sides thereof, it is possible to prevent the settling of the hygroscopic fiber even by repeated use, maintain a high cleaning effect, and increase the durability of the brush. Can be.
