Description

  The present invention relates to an optical disk repair device, and more particularly to an optical disk repair device that polishes and repairs a damaged local part of a substrate surface of an optical disk on which information is recorded or reproduced.

Usually, the structure of an optical disk is a recording layer for recording data by applying a metal film layer on a circular substrate, and a protective layer for protecting recorded data by applying polycarbonate or the like on the metal film layer. And In an optical drive used for reading data recorded on an optical disc, data recorded on a recording layer is read from a recording surface of the optical disc by a pickup lens.

The optical disc is frequently put in and out when used. Therefore, it is easily damaged if not handled carefully. As the number of uses increases, scratches having different depths are formed on the substrate. Such scratches make it difficult to read data in the optical drive and affect the convenience of use.

Therefore, an optical disk repair device has been developed. A conventional optical disk restoration device includes a polishing pad. The polishing pad comes into contact with the substrate of the optical disk, and the optical disk rotates to cause a polishing action by friction. In this case, an abrasive is used together. The object of removing scratches on the surface is achieved by polishing the reading surface of the optical disk by the frictional action of the polishing pad and the abrasive.

Usually, the position of the above-described polishing pad is fixed, and is mainly attached to the housing or lid of the optical disk restoration device. Such a structure cannot selectively polish a specific position on the reading surface of the optical disk. Therefore, a perfect polishing effect is achieved by polishing the entire reading surface of the optical disk and lengthening the polishing time. However, the scratches formed on the reading surface of the optical disc have different depths. If deep scratches exist and cannot be removed by a single polishing, the entire surface must be polished again. Therefore, the time and cost of the entire polishing process are increased. For this reason, in the industry, it is necessary to examine the drawbacks of the conventional optical disk restoration apparatus and take an improvement method.

An object of the present invention is to provide an optical disk restoration device capable of selectively polishing a specific position on a reading surface of an optical disk.

Therefore, the inventor has conducted intensive research in view of the drawbacks found in the prior art,
The present invention has been completed based on the knowledge that the problem can be solved by the optical disk restoration device constituted by the above.

Hereinafter, this device will be described in detail.
The optical disk restoration device according to claim 1 includes a housing, a rotational power unit that is provided in the housing and supports and rotates the optical disk, a lid provided on the housing, and a polishing unit provided on the lid. An optical disk repair device comprising:
A rail groove is formed on the surface of the lid facing the rotational power unit along the radial direction of the optical disk supported by the rotational power unit,
The polishing portion is constituted by a contact body formed on the upper surface with a columnar thread portion threaded on the outer peripheral surface, a polishing pad, and a fixing knob, and one end of the thread portion penetrates the rail groove. Then, the fixing knob is screwed so that the polishing portion can be positioned at an arbitrary position within the movable range along the rail groove.

By configuring the optical disk repair device as described above, the polishing position can be selectively converted, and the reading surface of the optical disk can be efficiently polished to remove scratches.

The optical disk restoration apparatus according to the present invention can selectively polish a specific position on the reading surface of the optical disk, thereby achieving efficient polishing, reducing the polishing time, and running cost required for polishing. This has the advantage that the convenience of the user is improved.

The present invention provides an optical disk restoration device capable of selectively polishing a specific position on a reading surface of an optical disk and achieving efficient polishing, and includes a housing, the housing, and A rotating power unit that supports and rotates the optical disc; a lid provided on the housing; and a polishing unit provided on the lid; the surface of the lid facing the rotating power unit has the rotational power A rail groove is formed along the radial direction of the optical disc supported by the portion, and the polishing portion is formed with a contact thread formed on the upper surface with a columnar thread portion threaded on the outer peripheral surface, a polishing pad, a fixing knob, And one end of the threaded portion penetrates the rail groove, and the fixing knob is screwed so that the polishing portion can be positioned at an arbitrary position within the movable range along the rail groove. Consists of.
In order to describe in detail the structure and features of such an optical disk restoration device, a specific example will be given and described below with reference to the drawings.

As disclosed in FIGS. 1 and 2, the optical disk restoration apparatus according to the present invention includes a housing 1, a rotating power unit 2 that rotates an optical disk provided in the housing 1, a lid 3 that is rotatably provided in the housing 1, And a polishing portion 4 provided on the lid 3.

The rotational power unit 2 includes a motor 21 and a rotation support plate 22 that is fitted to one end of a rotation shaft of the motor 21. As shown in FIGS. 1 and 2, the rotation support plate 22 projects at the center, and supports the optical disk 5 by fitting it onto the projection. When the optical disk 5 is supported by the rotating support plate 22 and polished, a fixed cap 23 is attached to the protrusion at the center of the fixed support plate 22. The fixing cap 23 may be a system in which the fixing cap 23 is screwed into the outer surface of the fixing support plate 22 and the inner wall of the fixing cap 23. The optical disk 5 is fixed on the rotation support plate 22 by the fixing cap 23, and the optical disk 5 is rotated in synchronization with the rotation of the rotation shaft of the motor 21.

The lid 3 is rotatably provided on the housing 1 in the form of a pivot or a shaft, for example. A rail groove 31 is formed on the surface of the lid 3 facing the optical disk 5 along the radial direction of the optical disk 5, and the polishing portion 4 is provided in the rail groove 31.

As disclosed in FIG. 3, the polishing unit 4 includes a contact body 41, a polishing pad 42, and a fixed knob 43. The contact body 41 includes a columnar thread portion 411 threaded on the outer peripheral surface, and the polishing pad 42 is provided on the contact body 41 along the axis of the thread portion 411. Further, one end of the thread portion 411 passes through the rail groove 31 and the fixing knob 43 is screwed. Therefore, the polishing portion 4 can be positioned at any location within the movable range along the rail groove 3.

When the upper surface opening of the housing 1 is closed by the lid 3, the polishing pad 42 is set to a height that just contacts the reading surface of the optical disc 1.

As disclosed in FIG. 4, the optical disk restoration apparatus having the above configuration fixes an optical disk in which a scratch has occurred in a local portion of the reading surface on the rotation support plate 22, and positions the polishing unit 4 at a position where it abuts against the scratch 6. Adjustment is performed and polishing is performed only on the position where the scratch 6 is formed. Therefore, the set polishing time is shorter than that of a conventional optical disk repair device, and polishing can be performed efficiently.

  The above is a preferred embodiment of the present invention, and does not limit the scope of implementation of the present invention. Accordingly, any modifications, changes, etc. that can be made by those skilled in the art that are made within the spirit of the present invention and that have an equivalent effect on the present invention shall belong to the scope of the claims for registration of the utility model.
