Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a magneto-optical disk cleaner for removing dirt and dust from the optical lens and magnetic head of the magneto-optical disk player. The magneto-optical disk referred to in the present invention includes all magneto-optical disks such as an MD (Mini Disk) and an MO (Magnet-Optical Disk).

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, as an optical lens cleaner of a magneto-optical disk player, there is one in which a cleaning member such as a flocked member or a woven cloth is adhered to an optical lens surface of a magneto-optical disk. Further, there is a magnetic head cleaner in which a cleaning member such as a raised member or a woven cloth is adhered to a magnetic head surface of a magneto-optical disk. These are commercialized as separate cleaners, and some products have both a cleaning member for an optical lens and a cleaning member for a magnetic head adhered to one magneto-optical disk.

[0003]

[Problems to be solved by the invention]

 However, in a magneto-optical disk cleaner in which both a cleaning member for an optical lens and a cleaning member for a magnetic head are adhered to a single magneto-optical disk as described above, the cleaning member for the optical lens is located within the signal recordable area. If attached, the writing (or recording) operation cannot be performed due to the structural factors of the magneto-optical disk player, so that the magnetic head cannot be cleaned.

For this reason, there is a product in which a cleaning member for an optical lens is stuck outside the signal recordable area. However, since the optical lens moves within the signal recordable area, the cleaning sticking outside the signal recordable area is performed. There was a further problem that the member could not contact the optical lens and the surface of the optical lens could not be sufficiently cleaned.

The present invention has been made in view of the above problems, and has as its object to provide a magneto-optical disk cleaner capable of reliably cleaning an optical lens and a magnetic head of a magneto-optical disk player. And

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the magneto-optical disk cleaner of the present invention records a simulation signal on a magneto-optical disk, affixes a cleaning member for an optical lens in the simulation signal area, and a magnetic head in an unrecorded signal area. A cleaning member is attached.

[0007] The magneto-optical disk cleaner constructed as described above is mounted on a magneto-optical disk player, and the optical lens can be cleaned with a reading (or reproducing) operation, and a magnetic head can be cleaned with a writing (or recording) operation. Can be cleaned.

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is an assembled perspective view of a magneto-optical disk cleaner according to an embodiment of the present invention, and is an assembled perspective view of a magneto-optical disk cleaner for an MD. As an optical lens cleaner, a cleaning member 2 for an optical lens such as a brush is adhered to the optical lens surface of the magneto-optical disk 1, and a fiber sheet or the like is applied to the magnetic head surface of the magneto-optical disk 1 as a magnetic head cleaner. The magnetic head cleaning member 3 is adhered. The magneto-optical disc cleaner for MD is formed by covering and fixing the cartridge 11 on the magneto-optical disc 1 on which the cleaning member is stuck.

FIG. 2 is a cross-sectional view of an embodiment of a magneto-optical disk cleaner according to the present invention during a U-TOC information reading operation. Recordable MD magneto-optical disk signal At least two tracks of signals are recorded in a part of the recordable area 4. In FIG. 2, signals are recorded on tracks 1 and 6 and tracks 2 and 7. I have.

In order to attach the optical lens cleaning member 2 to the track No. 6, a signal amount for securing a width at least equal to the width of the optical lens cleaning member 2 is recorded. In addition, the signal amount of the track 2-7 may be appropriate, and voice and music are recorded.

Next, the track numbers of the two tracks of the track No. 1 and the track No. 2 are changed by U-TOC (User's-Table of Contents) information processing. That is, the track on which voice or music is recorded is track No. 6, and the track on which the optical lens cleaning member 2 is adhered is track No. 7. By exchanging the tracks, the operation of the reproduction button of the MD player causes the optical lens 9 to skip the tracks 2 and 7 on which the optical lens cleaning member 2 is adhered, and start the operation of reproducing the tracks 1 and 6. FIG. 3 is a sectional view showing an embodiment of the magneto-optical disk cleaner of the present invention during cleaning of the optical lens of the disk. The optical lens 9 contacts the optical lens cleaning member 2 while skipping track 2-7. Then, the surface of the optical lens 9 can be cleaned.

FIG. 4 is a cross-sectional view of the magneto-optical disk cleaner according to an embodiment of the present invention during magnetic head cleaning of the disk. The recording operation is performed in the signal unrecorded area 8 by operating the recording button of the MD player. enter. At this time, the magnetic head 10 comes into contact with the magnetic head cleaning member 3, and the surface of the magnetic head 10 can be cleaned.

The magnetic head cleaning member 3 such as a fiber sheet attached to the magnetic head surface of the MD disk is provided with a track on which signals are recorded from the signal recordable area 4, that is, the U-TOC area 5 (this embodiment). In the example, tracks 1 and 6 and tracks 2 and 7) and a signal unrecorded area 8 are attached to all surfaces. The surface of the magnetic head 10 can be cleaned in a recording time of about 10 seconds, and cleaning can be repeatedly performed until the free space of the signal unrecorded area 8 becomes full.

As described above, by selectively using at least two track areas on which signals are recorded on one magneto-optical disc 1 and signal unrecorded areas 8, the optical lens 9 can be formed by one magneto-optical disc cleaner. In addition, the magnetic head 10 can be reliably cleaned.

[0015]

[Effect of the invention]

 As described above, when the magneto-optical disc player is cleaned using the magneto-optical disc cleaner of the present invention, a cleaning member such as a flocked member or a woven cloth is attached to the optical lens surface with the reading (or reproducing) operation. As the writing (or recording) operation comes in contact with the magnetic head surface, the cleaning member such as a brushed member or a woven cloth surely comes into contact with the magnetic head surface, resulting in dust or dirt adhering to the optical lens or magnetic head. Dirt can be efficiently removed. For this reason, it is possible to prevent the occurrence of errors and the like and the deterioration of sound quality.
