Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an electronic filing system for storing documents, data, etc. in an optical disk for efficient operation of documents such as retrieval and inquiry, more specifically, the system. Make up,
The present invention relates to an access method for a collective optical disk device that centrally manages a plurality of optical disks.

(Prior Art) In an electronic filing system using a collective optical disk device, conventionally, each user (terminal) directly designates the name of a specific optical disk, and the drive device in the optical disk and the collective optical disk device is specified. Was occupied and used.

(Problems to be solved by the invention) This means that when each user wants to retrieve a document or the like stored in the same optical disk, only the user who first starts using the optical disk occupies it. Other users had to wait until the first user finished searching for the optical disk, and needed to access again. Therefore, there is a drawback that each user has to wait unnecessarily when the above situation occurs.

The object of the present invention is to solve the above-mentioned drawbacks. Even if access conflicts with the same disk, there is no need to wait as in the conventional device, and the number of mounts can be reduced as compared with the conventional device. An object of the present invention is to provide an access method for a collective optical disk device which can reduce mechanical damage to the device.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the access method of the collective optical disk device according to the present invention is connected to a plurality of terminal devices, each terminal device and an information connection line, A plurality of optical discs are built in, and in accordance with an access request from the terminal device, a collective optical disc device that automatically mounts one of the optical discs in an optical disc drive device in the device. In the electronic filing system, when the same optical disk receives access requests from a plurality of terminals, the access requests are stored in the information storage unit, and after processing all access requests, the optical disk drive device is processed. It is configured to demount the mounted optical disk.

That is, instead of occupying the optical disk for each user with the collective optical disk, if the same optical disk medium as the first user is used, the access request from the later user is accepted and the first user finishes the use. However, if it is used by a later user, continue to use the drive device in the optical disk and the collective optical disk and return the optical disk to the storage cell of the collective optical disk only when all access requests are exhausted. I have to.

(Example) Hereinafter, the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a block diagram of an electronic filtering system showing an embodiment of an access system of a collective optical disk device according to the present invention.

The collective optical disk controller 1 including the collective optical disk 2 and the information storage unit 10 constitutes a collective optical disk device.

The terminal [1] 11 includes a control unit 4, a monitor 5 and a keyboard 6.
The terminal [2] 12 is also composed of the control unit 7,
It is composed of a monitor 8 and a keyboard 9.

The terminals 11 and 12 and the collective optical disk device are connected via the information exchange line 3.

When accessing the collective optical disk device from the terminal, data specifying the optical disk is input from the keyboard and sent to the collective optical disk controller 1 via the control unit and the information exchange line 3.

FIG. 2 is a schematic view of the collective optical disk device, in which the mechanism part for taking out the optical disk and mounting it on the drive device is extracted and shown. There are cells 20 each containing an optical disk, in this example there are 0-5. The optical disk accommodated in each cell is taken out by an accessor and mounted on the drive 24.
In this example, the optical disk 23 is the access target.

Now, the operation in the case where the terminal 1 makes an access request to the optical disk 23 accommodating the cell 0 and then the terminal 2 makes an access request to the same optical disk 23 will be described.

When there is an access request from the terminal 1 to the optical disk 23, the collective optical disk controller 1 stores the optical disk name and the used terminal 1 in the information storage unit 10 corresponding to the drive 24, and further in response to the access request from the terminal 2. However, the same is stored. When the access processing from terminals 1 and 2 is completed and all access requests are released, the optical disk of drive 24 is
Demount 23.

The present embodiment is an example in which the number of terminals is 2 and the number of drives of the collective optical disk device is 1, but the same can be applied even if the number of terminals and the number of drives are increased.

(Effects of the Invention) As described above, according to the present invention, simultaneous access from multiple users of an optical disk is enabled, and not only the waiting time for each user is reduced, but also the total number of mounts is reduced. There is an effect that the mechanical damage given to the accessor of the collective disk device and the optical disk is reduced.
