Among such information filing devices, optical disk devices, which use optical disks as information storage media to record necessary information, and also search and reproduce the recorded information, are notable for their significantly large recording capacity. It has been widely put into practical use.

Information is recorded using this optical disk device by optically reading and scanning the surface of the document to be recorded with a laser beam, converting the black and white information on the document surface into an electrical signal (analog signal), and converting this analog signal into an electrical signal (analog signal). After FM modulating the recording signal, the laser beam generated by the laser light source is 0N-OF modulated using the recording signal, and the recording layer of the optical disk rotating at a constant speed is irradiated with this. This is done by changing the optical properties of the site.

To reproduce the recorded document, an optical disk is rotated at a constant speed, a beam of constant intensity is irradiated along the track on the optical disk, and the modulation state of the reflected light from the recorded part is converted into an electrical signal. This is done by reading out the information.

First, the configuration of a conventional optical disk device having the above-mentioned functions will be explained with reference to FIGS. 4 to 7.

By rotating the information storage medium while suctioning, the entire surface of the information storage medium can be cleaned at once.

Therefore, foreign matter such as dust attached to the surface of the information storage medium, which has been difficult to remove in the past, can be cleaned simultaneously during recording and reproduction of the information storage medium.

(Description of Embodiments) Hereinafter, embodiments of the information storage medium of the present invention will be described in detail with reference to the drawings.

In Fig. 1, numeral 1 is a disc-shaped optical disc as an information recording medium, which is usually housed in a cassette case (cartridge) 2 and locked to prevent foreign matter from adhering to it. sealed in condition.

Reference numeral 3 denotes a main body case that covers the mechanical section of the optical disk device, and a part thereof is provided with an insertion/removal opening 4 for inserting and removing the cassette case 2, and a shutter 5. This shutter 5 is closed except when inserting or ejecting the cassette case 2, and prevents foreign matter such as dust from entering the main body of the apparatus.

Reference numeral 6 denotes a base on which the mechanical part of the optical disk device is mounted, and is fixed to the main body case 3 via rubber gaskets 7 such as rubber feet in order to enhance the vibration-proofing effect.

Reference numeral 9 denotes a turntable on which the optical disc 1 is placed, crimped by a clamper 11, and rotated. Note that while the optical disc 1 is rotating, the cassette/nod case 2 is supported by a support 10.

Further, the optical head 15 for recording and reproducing data on and from the optical disc 1 is adapted to slide in the radial direction of the optical disc 1 on the exposed bottom or top surface of the optical disc 1, as shown in FIG.

Note that the illustrated optical disk device actually includes the above-mentioned case transport/opening/closing unit, unit displacement means, optical disk drive device, and optical disk drive unit. − This includes a card moving device, etc., but these are omitted on the drawing.

As shown in the figure, the optical disc device of the present invention described above has a suction means (
This embodiment is characterized by the provision of a suction nozzle 12).

That is, the suction nozzle 12 is connected to a fan 13 provided on the side surface of the main body case 3 via a suction pipe 14, and its tip opening faces the exposed surface of the optical disc 1.

The tip installation device of this suction nozzle 12 only needs to face the exposed surface of the optical disk 1, for example, the optical head 1
Any position such as the vicinity of 5, the opposite side of the optical head 15, or the upper or lower surface of the optical disc 1 can be selected.

To actually operate the optical disk device of the present invention described above, first, the cassette case 2 containing the optical disk 1 is inserted through the insertion/ejection opening 4 of the main case 3.

Then, the cassette case 2 is taken into the main body of the device by the action of the feed roller 98, etc., and the lock is released, and the central part or the radius part opens at an appropriate angle, and the optical disc with a part of the surface exposed. 1 is placed on the turntable, and the cassette case 2 is placed on the support 10.

In this state, the upper surface of the central portion of the optical disc 1 is clamped by the clamper 11, and the optical disc 1 is rotated by driving the motor 8.

Next, the optical head 15 slides onto the exposed surface of the rotating optical disc 1, thereby performing recording and reproduction.

When the presence of foreign matter is detected on the surface of the optical disc 1, a fan drive motor (not shown) is rotated,
When the fan 13 is activated, the suction nozzle 12 suctions the exposed surface of the optical disc 1, and the foreign matter is removed by the fan 1.
It is removed in three directions and efficient leaning is achieved.

Note that it is of course possible to keep the fan 13 constantly rotating during recording/playback of the optical disc 1, and to continue recording/playback and cleaning operations at the same time.

In the embodiment described above, it is particularly desirable that the suction nozzle 12 be provided facing the bottom surface of the optical disk 1. With this configuration, the bottom surface of the horizontally rotating optical disk 1 is sucked, so that the gravity of the foreign object itself is absorbed. The removal effect can also be enhanced by using the same method, and even more efficient lean can be achieved.

Further, as shown in FIG. 2, it is preferable that the tip opening of the suction nozzle 12 has an elongated shape whose suction width is equivalent to the radial width of the optical disc 1. The entire surface and circumference of the optical disc 1 is cleaned, making it possible to completely remove attached foreign matter.

Furthermore, as shown in FIG. 3, the distance between the tip of the suction nozzle 12 and the surface of the optical disk 1 is equal to the surface runout distance of the optical disk 1! This completely eliminates the risk of the suction nozzle 12 damaging or abrading the surface of the optical disc 1 when the optical disc 1 is deflected, thereby increasing the reliability of the cleaning effect. improves.

It is preferable that the fan 13 that suctions the suction nozzle 12 is equipped with a filter 16, so that foreign matter sucked by the suction nozzle 12 is adsorbed by the filter 16, and foreign matter such as dust from the outside is also absorbed by the filter 16. Since there is no possibility that the optical disk 16 will be attracted by the optical disc 16 and enter the apparatus main body, it is possible to improve the cleaning effect and to obtain the effect of protecting the optical disc 1 and the apparatus main body.

〔Effect of the invention〕

As described above in detail with reference to the embodiments, the information processing device of the present invention is provided with a suction means facing the rotating information storage medium, and the suction width of the suction means is approximately equal to the radial width of the information storage medium. Since the widths are the same, by rotating the information storage medium while suctioning, the entire surface of the information storage medium can be cleaned at once.

Therefore, foreign matter such as dust attached to the surface of the information storage medium, which was previously difficult to remove, can be cleaned simultaneously during recording and playback of the information storage medium, greatly improving the added value of the information processing device. At the same time, it is also possible to improve the durability of the optical disc.
