Abstract

PURPOSE:To automatically set an optional medium to the read/write station by having a storage cell number in a volume management file as management information when an optical disk is stored in the medium storage cell. CONSTITUTION:When plural optical disks are supplied to a gathering type optical disk device 1, all mediums are stored in a medium storage cell 21. When an optional optical disk in the medium storage cell 21 is set to a read/write station 22, a volume management file access means 4 uses a medium name 32 as the key to read a management record 31 from a volume management file 2. The volume management file access means 4 recognizes a medium storage cell number 23, where the optical disk is stored, in accordance with the management record 31 and transfers it to a setting request means 5, and this means 5 designates the medium storage cell number 23 to request the gathering type optical disk device to set the optical disk. Thus, the optional medium is automatically set to the read/write station.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention provides read/write processing of an optical disk stored in a medium storage cell of a collective optical disk device in a computer system having a collective optical disk device. The present invention relates to an optical disk medium loading control device that automatically loads a station.

(Prior Art) Conventionally, optical disk devices do not have a medium storage cell like collective optical disk devices, so each time an optical disk of a different medium is used, it is necessary to manually load and unload the optical disk into the optical disk device. did not become.

(Problem to be Solved by the Invention) The conventional optical disk device described above could only load one optical disk at a time, so when using another optical disk, the currently installed optical disk must be inserted and removed, and the medium must be loaded again. The disadvantage was that it had to be inserted into the read/write station.

SUMMARY OF THE INVENTION An object of the present invention is to provide an optical disk medium device control device that stores a plurality of optical disks in a collective optical disk device and automatically loads any medium into a read/write station.

(Means for Solving the Problems) To achieve the above object, an optical disk medium loading control device according to the present invention includes a medium storage cell that stores a plurality of optical disks, and a read/write station that reads and writes data to the optical disk. a collective optical disk device comprising: a medium recognition means for recognizing a medium storage cell number of an optical disk stored in the medium storage cell; and a management record for recognizing the optical disk according to the medium storage cell number recognized by the medium recognition means. a volume management file for managing the media storage cell number of the management record; a volume management file access means for reading and writing the media storage cell number of the management record; and a volume management file access means for reading and writing the media storage cell number of the management record; and mounting request means for designating the medium storage cell number read by the access means and requesting the collective optical disc device to mount the optical disc.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of optical disk medium loading control snowmaking according to the present invention, FIG. 2 is a diagram for explaining the collective optical disk device of FIG. 1, and FIG. FIG. 3 is a diagram for explaining management records of a volume management file of FIG.

The optical disk medium mounting control device according to the present invention is comprised of a collective optical disk device, a volume management file 2, medium recognition means 3, volume management file access means 4, and mounting request means 5.

As shown in FIG. 2, the collective optical disk device 1 is composed of a medium storage cell 2 and a read/write station 22. The medium storage cell 21 can store N optical discs.

The read/write station 22 is for reading and writing data to the optical disk), and reading and writing to the optical disk is performed by loading the optical disk from the medium storage cell 21 into the read/write station 22. The medium storage cell 2 of this collective optical disk device 1 can always store N or less optical disks.

The volume management file 2 is for managing the optical disk using a management record 31, and as shown in FIG. 8, it has the storage cell number 33 of the medium storage cell 21 using the medium name 32 of the optical disk as a key. .

Next, the operation of the control device according to the present invention will be explained together with the configuration of each part.

When a plurality of optical disks are inserted into the collective optical disk device 1, all the media are stored in the medium storage cell 21. The optical disc is stored in the medium storage cell number 23 of the medium storage cell 21.
are stored in this order.

When an optical disc is first stored in the collective optical disc device 1, the optical disc is stored in the read/write station 22.
are installed in sequence. The medium recognition means 3 sends the optical disks to the read/write station 2 in the order of medium storage cell number 23.
2 and recognizes the media name.

When the medium recognition means 3 recognizes the medium name, it passes the medium storage cell number 23 and the medium name to the volume management file access means 4. The volume management file access means 4 accesses the management record 3 using the medium name 32 of the optical disk as a key.
The medium storage cell number 33 is set to 1 and written to the volume management file 2.

Thereafter, management records 31 are written to the volume management file 2 for the optical disks in the medium storage cell 21 in the same manner.

When an arbitrary optical disk in the medium storage cell 21 is loaded into the read/write station 22, the volume management file access means 4 reads the management record 31 from the volume management file 2 using the medium name 32 as a key. The volume management file access means 4 is the management record 3]
From there, the medium storage cell number 23 in which the optical disk is stored is recognized and passed to the mounting request means 5.

The loading request means 5 specifies the medium storage cell number 23 and requests the collective optical disk device to load an optical disk.

(Effects of the Invention) As explained above, the present invention provides a system for storing a storage cell number as management information in a volume management file when storing an optical disc in a medium storage cell in a collective optical disc device that can store a plurality of optical discs. This has the advantage that any medium can be automatically loaded into the read/write station.
