DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk device for pulling out a disk from a disk holder for recording and reproduction and a disk holder used in the disk device, and more particularly to a disk holder having an improved insertion portion for the disk. And a disk device.

[0002]

2. Description of the Related Art In recent years, various disk devices for recording and reproducing data on and from a recording medium such as a disk have been widely used.
A tray type and a holder type are known as devices for loading a disk in a horizontal direction with respect to a recording / reproducing unit. In the tray type, a disc is placed on a disc tray protruding from the front of the disc device, and the disc tray is returned into the device, whereby the disc is transported to the recording / reproducing unit. In the holder type, a disk holder holding a disk from its surroundings is loaded in a disk device in advance, the disk is pulled out from the disk holder by a mechanism inside the disk device, and the disk is transported to a recording / reproducing unit. is there.

The disk holder used in the holder type has an advantage that it can be made thinner than the disk tray used in the tray type, so that the disk device can be downsized and a plurality of disks can be loaded. It is suitable for an autochanger-type disk device that performs the operation. This autochanger type disk device is convenient because it is not necessary for the user to insert and remove disks one by one in order to exchange disks for recording and reproduction.

[0004] As such a disk device, a disk device provided with a disk magazine capable of accommodating a plurality of disk holders in a multilayer structure is generally used. This disk device includes a disk magazine, a mounting section to which the disk magazine can be attached and detached, a transport section for transporting a disk holder, a recording / reproducing section including a pickup, a turntable, a clamper, and the like.
The disk magazine to be mounted on the mounting portion is box-shaped, and a plurality of grooves are formed in the left and right inner side surfaces in the horizontal direction. Since both ends of the disk holders for individually storing the disks are inserted into these grooves, a large number of disk holders are stored in the disk magazine in a stacked manner. The individual disk holders housed in a stacked manner as described above have, at one end thereof, an insertion portion capable of inserting and discharging a disk in a direction (horizontal direction) parallel to the main surface thereof, and a disk magazine. It is provided so as to be able to be taken in and out in the same direction as the direction of insertion and ejection of the disc.

[0005] In the above-described disk device, when recording and reproducing a disk, first, a disk magazine is mounted on a mounting portion. Then, the disc holder holding the disc for which recording or reproduction has been instructed is pulled out toward the recording / reproducing section by the transport section, and the disc is clamped by the turntable and the clamper.
Thereafter, only the disc holder is returned into the disc magazine while the disc is being ejected by the transport unit, and recording and reproduction of the disc are performed by the pickup.

Further, when recording / reproducing another disk or when removing the disk magazine from the mounting portion, the empty disk holder is again moved in the horizontal direction toward the recording / reproducing portion, and the disk held on the turntable is moved again. From the insertion section. Then, after the disk is released, the disk holder containing the disk is returned to the disk magazine, and recording / reproduction of another disk is performed in the same procedure as described above, or the disk magazine is removed. .

[0007]

However, the above disk device has the following points to be improved. That is, as described above, when returning the disc held on the turntable to the disc magazine, the disc holder moves in the horizontal direction, and the disc is stored in the disc holder from the insertion portion. This disk holder is inserted into the grooves on the left and right inner surfaces of the disk magazine.However, in consideration of making the disk magazine thinner and preventing the disk from vibrating in the disk holder, the grooves need to be formed narrowly. The positional accuracy required for inserting the disc into the holder is high. However, when the disc is not accurately held on the turntable or when the disc itself is deformed, the height difference between the side surface of the disc and the insertion portion of the disc holder occurs. When such a deviation occurs, there is a possibility that the end of the disk hits the end on the insertion portion side of the disk holder, or the disk cannot be stored in the disk holder.

To cope with this, if the frontage of the insertion portion of the disk holder is widened, errors due to the above-mentioned misalignment can be absorbed, and the possibility of causing a problem can be reduced. However, when the frontage of the insertion portion is widened in this way, the thickness of each disk holder in the height direction is increased. Then
It is necessary to increase the height of the disk holder for accommodating a large number of disk holders stacked therein, resulting in an increase in the size of the entire disk device.

The present invention has been proposed to solve the above-mentioned problems of the prior art.
An object of the present invention is to provide a disk device capable of reliably returning a disk at a reproduction or recording position to a disk holder without increasing the size of the device.

Another object of the present invention is to provide a disc holder which can reliably insert a disc and does not increase the size of a disc device.
