And the number of volumes indicating the number of volume names generated corresponding to the virtual volume names.

Next, the operation of the present embodiment will be described in detail with reference to FIGS. 1, 2, 3 and 4. First, the control unit 21 of the optical disk virtual volume management device 2
The virtual volume setting parameter of the setting request is received from the virtual volume table setting unit 22. The virtual volume table setting unit 22 generates a volume name of a serial number corresponding to the number of volumes according to the specified virtual volume name, the number of volumes, and the input / output division, and uses the volume name to indicate the collective optical disc device 1 indicated by the device number of the parameter.
Is initialized, and the cell position indicating the storage position of the optical disk at the time of initialization, the device number, the virtual volume name, the volume name, and the mounting category are set in the virtual volume table 25 as not mounted. If “0” is specified as the number of volumes in the virtual volume setting parameter, the corresponding virtual volume is specified from the virtual volume table 25 by using the specified device number, the virtual volume name including the virtual ID and the input / output section as a key. Delete the name and volume name. When the optical disks of all devices specified in the parameters are initialized, the creation of the virtual volume table 25 is completed, and a completion notification is passed to the control unit 21. The control unit 21 sends a notification of completion of the initialization of the optical disc to the host device 3.
Pass to.

When the control unit 21 receives the virtual volume name of the loading request from the host device 3, it passes this virtual volume name to the execution virtual volume table creation unit 23. The execution virtual volume table creation unit 23 extracts the name of the virtual volume to be loaded from the virtual volume table 25 as a key, sets a loading request in the corresponding device number, virtual volume name, volume name, cell position, and mounting category, and executes the execution virtual volume table. When the completion notification is passed to the control unit 21 when the creation is completed and the creation is completed, the control unit 21 passes control to the optical disc designating unit 24. The optical disc designating unit 24 refers to the execution virtual volume table 26, sequentially checks the mounting category from the first volume name, and sets the volume name and the device number in the loading command when not mounted or when a loading request is made, and When the optical disk control unit 13 is instructed to load an optical disk into the read / write unit 11, the mounting is displayed in the mounting section of the execution virtual volume table 26 and the mounting is also displayed in the mounting section of the virtual volume table 25. Execution virtual volume table 26
When the loading of the optical disks of all the volume names is completed, a completion notification is passed to the control unit 21. The control unit 21 passes a mounting completion notification to the host device 3. The host device 3 executes a job or the like. When executing the next job or the like, the host device 3 may specify a virtual volume name necessary for executing the job.

When the control unit 21 receives the virtual volume name of the ejection request from the higher-level device 3, it passes this virtual volume name to the execution virtual volume table creation unit 23. The execution virtual volume table creation unit 23 extracts the virtual volume name to be ejected from the virtual volume table 25 as a key, sets an ejection request to the corresponding device number, virtual volume name, volume name, cell position, and mounting category, and executes the execution virtual volume table. When the completion notification is passed to the control unit 21 when the creation is completed and the creation is completed, the control unit 21 passes control to the optical disc designating unit 24. The optical disc designating unit 24 refers to the execution virtual volume table 26, sequentially checks the mounting category from the first volume name, sets the volume name and the device number in the ejection command at the time of an ejection request, and sets the optical disc control unit of the collective optical disc device 1 When the optical disk is ejected from the read / write unit 11, the ejection is displayed in the mounting section of the execution virtual volume table 26 and the ejection is also displayed in the mounting section of the virtual volume table 25. When the ejection of the optical disks of all the volume names in the execution virtual volume table 26 is completed, a completion notification is passed to the control unit 21. The control unit 21 passes a discharge completion notification to the host device 3.

An operation example of the present embodiment will be described with reference to FIG. For example, assume that the input volume names JBAI01001 and JBAI02001 required for executing job A are registered in the virtual volume table with the virtual volume name “JBAI”. Also, the output volume name J
It is assumed that the virtual volume names of BAO01001 and JBAO2001 are registered in the virtual volume table as “JBAO”. Before executing the job A, “JBAI” and “JBAO” are set as the execution virtual volume names in the host device 3.
Requesting the optical disk virtual volume management device 2 to load JBAI1001 and JBAI0200
1, the optical disks having the volume names of JBAO00101 and JBAO02001 are loaded in the read / write unit 11.

The input volume names required to execute job B are JBAO0011, JBAO2001, and the output volume names JBBO01001, JBBO
It is assumed that 02001 is registered in the virtual volume table as the virtual volume name “JBBO”. Job B
Prior to the execution of, the upper device 3 requests the optical disk virtual volume management device 2 to load “JBAO” and “JBBO” as the execution virtual volume names, thereby making JBBO010.
01, an optical disk having a volume name of JBBO02001 is newly loaded in the read / write unit 11.
