Abstract

PURPOSE: To perform reading and writing in a system of a combination of plural optical disks by possessing a disk control means for recording and reproducing plural optical disks with a recording and reproducing means arranged in a specified combination. CONSTITUTION: Optical disks from a housing part 10 are held according to their individual groups and are carried to be in front of optical disk drive devices 12 to 14 by a carrier mechanism 11 having areas for holding optical disks according to their individual groups. The optical disks held by a carrier part are loaded into the devices 12 to 14 classified in the individual groups. These optical disks are housed into their original positions in the housing part 10 in the reverse sequence of operation. The moving direction of the mechanism 11 is orthogonal to the optical disk moving direction to the housing part 10 for housing the optical disks. Then, since the moving direction of the mechanism 11 and the housing direction from the mechanism 11 to the devices 12 to 14 cross orthogonally, the movement is simple, and the mechanical configuration is simplified due to simplicity of each individual mechanism.

(1) First Embodiment Of FIGS. 1 to 4, FIG. 1 shows a state in which an optical disc in an optical disc changer device is stored in a storage unit.
2 shows that a certain group of optical disks is held in the transport section, FIG. 3 shows that the transport section has moved to the front of the optical disk drive apparatus, and FIG. 4 shows that a certain group of optical disks is loaded in the optical disk drive apparatus. It represents what has been done.

In FIG. 1, 1 is a first optical disk, 2
Is the second optical disc, 3 is the third optical disc, and 4 is the fourth optical disc.
Optical disk, 5 is a fifth optical disk, 6 is a sixth optical disk, 7 is a seventh optical disk, 8 is an eighth optical disk, 9 is a ninth optical disk, 10 is a storage section for storing an optical disk, 11 Is a transport unit for simultaneously transporting a plurality of discs, 12 is a first optical disc drive device for reading and writing optical discs, 13 is a second optical disc drive device for reading and writing optical discs, and 14 is an optical disc reading and writing A third optical disc drive device 15 for performing the above is a housing.

Each of the first to ninth optical disks 1 to 9 is divided into groups by the same number as the number of optical disk drive devices. In this case, the first
The optical disc 1, the fourth optical disc 4, and the seventh optical disc 7 belong to the same group, and similarly, the second optical disc 2, the fifth optical disc 5, the eighth optical disc 8, and the third optical disc
The optical disc 3, the sixth optical disc 6, and the ninth optical disc 9 are divided into three groups.

When the optical disk is not read or written, each optical disk is stored in a predetermined position in the storage unit 10, as shown in FIG. The transport mechanism 11 has an area for holding the optical discs for each group. As shown in FIG. 2, the transport mechanism 11 holds the optical discs for each group from the storage unit by an unillustrated mechanism, and as shown in FIG. It is conveyed to the front of the optical disk drive devices 12 to 14 by the mechanism shown. As shown in FIG. 4, the optical discs held by the transport unit are loaded into the optical disc drive devices 12 to 14 for each group by a mechanism (not shown). In this way, the optical disks are always loaded into the optical disk drive devices 12 to 14 for each group at the same time. Then, in the reverse order, the transport mechanism 11 causes the optical disk drive devices 12-1 to 12-1.
Each optical disk is taken out from the disk 4, transported to the entire surface of the storage unit 11, and stored in the original position of the storage unit 11. The ejected optical disks are stored in the storage unit for each original group.

Of course, the number of optical disk drive devices may be three or less or more. In that case, the number of optical disks arranged in the transport unit 11 may be adjusted to the number of optical disk drive devices, and the number of optical disk groups arranged in the storage unit 10 may be adjusted to an integral multiple of the number of optical disk drive devices.

Further, by adjusting the arrangement intervals of the optical disks of each group in the storage section 10 and the arrangement intervals of the optical disks in the transport section 11 to the arrangement intervals of the respective optical disk drive devices, respectively, there is no complicated mechanism. It is possible to smoothly transport and load the optical disc of each group.

Further, since the moving direction of the transport mechanism 11 (vertical direction in FIG. 1) and the moving direction of the optical disc to the storage section for storing the optical disc (horizontal direction in FIG. 1) are orthogonal to each other, the transport mechanism is also provided. Since the moving direction of 11 (vertical direction in FIG. 1) and the storing direction from the transport mechanism 11 to the optical disk drive device (horizontal direction in FIG. 1) are orthogonal to each other, the operation is simplified and the simplicity of each mechanism is improved. The simplicity simplifies the structure of the mechanism.

In the above embodiment, the recording / reproducing medium is specified as the rewritable type rewritable type optical disk, but even if the recording / reproducing medium is a floppy disk, an optical card, an IC card, etc. If the transport mechanism, the recording / reproducing device, and the fixed-size storage section are provided, the effect of the present invention can be obtained in addition to the characteristics peculiar to each recording / reproducing medium.

Is different from that in FIG.

In FIG. 5, a storage unit 10 stores nine (1 to 9) magneto-optical disks divided into three groups, and a transport mechanism 11 has three optical disk drives 12 to.
14 are arranged corresponding to each group. Further, the transport mechanism 11 needs to be able to transport only three stages of magneto-optical disks. For example, the magneto-optical disks 1, 4, and 7 are simultaneously housed and loaded in the optical disk drive to be driven, and the magneto-optical disks 1, 4 and 7 are respectively loaded with 3 disks. Seed data can be recorded, or the same data can be simultaneously recorded on three magneto-optical disks. Alternatively, the information data of each of the three types of magneto-optical disks 1, 4, 7 can be delivered to an external data utilization device. Then, after the information data is recorded / reproduced in the reverse order, it can be housed and ejected from the transport mechanism 11 at the same location of the original optical disc of the storage unit 10 at the same location. After that, the next magneto-optical disk 2,
The transport mechanism 11 is moved to the stages of 5 and 8, each magneto-optical disk is housed in the drive in the transport mechanism 11, and the same operation as described above is performed. In the above embodiment, the three groups are described, but the present invention is not limited to this, and it is needless to say that the same effect can be obtained even if the groups are divided into a plurality of groups.

In this way, the magneto-optical disks in the storage unit for accommodating a large number of sheets are divided into a plurality of groups, and the same number of a plurality of drives are provided, so that the operation of the transport mechanism can be simplified and in the case of reproduction. Can deliver and send prompt information data, and can record a large amount of information data at a time when recording. Therefore, even with an autochanger that accommodates the majority of magneto-optical disks, it is possible to maintain stable operation and reliability for a long time with a simple mechanism and a small amount of change in movement.
