Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information recording medium including a disk such as a magnetic disk, an optical disk, a magneto-optical disk, and more particularly to a disk cleaning mechanism. In recent years, with the spread of electronic devices such as personal computers and audio devices, disk-shaped recording media such as magnetic disks, magneto-optical disks, and optical disks have been used. These recording media have advantages such as easy handling and low cost. For example, a magnetic disk such as a floppy (registered trademark) disk is housed and used in a flat disk cartridge (hereinafter abbreviated as “cartridge”) so that dust and scratches do not adhere to the recording / reading surface of the disk. Sold. On the other hand, an optical disk storing music, video, etc. is housed in a case at the time of sale, but when it is loaded into a disk drive, only the optical disk is inserted into the disk drive. When foreign matter such as dust or hand dust adheres to the information recording surface of the optical disc,
The user wipes off the dirt using a cloth or the like. Further, the information recording surface has a structure in which a protective layer is formed on a reflective film for recording information, and the information itself is protected from scratches and dust. In some hard disk devices, a magnetic disk and a magnetic head are housed in a case, and information is recorded and reproduced with a computer or the like via an interface. In this case, the magnetic disk cannot be removed from the case, but dust and the like are prevented from entering the case, and access errors are unlikely to occur. [0005] As described above, in various disc-shaped recording media, various devices have been devised to prevent dust and the like from adhering to the information recording surface. And
In accordance with the structure of each recording medium, the disk drive is also assembled in a structure capable of loading an information recording medium. By the way, in a state where the usage of the recording medium is diversified, an information recording medium and a disk drive more suitable for the usage are proposed even if the recording medium has a structure other than that described above. Should be. The proposed information recording medium is desired to have a low-cost structure that can be easily used with a simple mechanism and can remove foreign substances adhering to the disk as a medium to be used normally. Accordingly, an object of the present invention is to provide an inexpensive and simple information recording medium capable of removing foreign matter adhering to a disk. [0008] An information recording medium of the present invention comprises a disk having an information recording surface for recording information on a circular upper surface and / or lower surface, and a foreign matter adhering to the information recording surface. A cleaning member that removes the disk, and the cleaning member is loaded into the disk drive together with the disk, the cleaning member rotatably holding the disk, so that the upper part of the disk A housing provided so as to cover a part of the disk with a lower surface interposed therebetween, and an inner surface facing the information recording surface of the housing in contact with the information recording surface from the information recording surface when the disk rotates And a foreign substance removing unit provided to remove the foreign substance. Here, the “housing” of the cleaning member may be rotatably fixed to the disk, or may be detachably provided. The cleaning member is preferably loaded so that the magnetic head or the optical head of the disk drive is positioned immediately before the access area for accessing the disk, that is, before the rotation direction of the disk, when the disk is loaded into the disk drive. . According to the information recording medium of the present invention, since the housing is provided so as to cover a part of the disk, it is inexpensive with a simple mechanism as compared with the case where the entire disk is covered with the housing. An information recording medium having a structure can be provided. Further, a foreign matter removing portion is provided on the inner surface of the housing facing the information recording surface so as to contact the information recording surface and remove foreign matter from the information recording surface when the disc is rotated. The portion comes into contact with the entire information recording surface of the disc, and foreign matter can be removed over the entire circumference of the disc. Further, since the disk is held by the housing, when the user carries the disk, the user can carry the disk without touching the disk by gripping the housing. Can be prevented. In addition, since the cleaning member is loaded in the disk drive together with the disk, the foreign material removal unit can remove the foreign material adhering to the information recording surface while the disk is driven to rotate. When the information recording medium is loaded in the disk drive, if a cleaning member is disposed immediately before the area where the disk is accessed in the disk drive, dust, dust, etc. are removed from the disk surface immediately before access. It can be removed, and an access error due to foreign matter can be suppressed. 1 and 2 are a perspective view and a sectional view, respectively, showing a preferred embodiment of an information recording medium of the present invention.
