Referring to FIG. 3, the storage area management table 11 stores medium name information 12 and shelf number information 13 in a table format for each storage medium.

Referring to FIG. 4, the storage area status table 14 stores shelf number information 15 and shelf status information 16 in a table format for each shelf.

Next, the operation of the thus configured storage medium replacement system of this embodiment will be described.

First, the storage area management table creation means 3 reads one storage medium table 7 from the medium management storage means 1, and if the storage medium is information stored in the collective storage device to be replaced, the table is read. Then, the medium name information 8 and the shelf number information 9 are extracted and written into the storage area management table 11 of the storage area management storage unit 2. This processing is performed for all the storage medium tables 7 existing in the medium management storage means 1, and when the processing is completed, the control is transferred to the storage area state table creation means 5.

The storage area state table creating means 5 matches the shelf state information of the collective storage device stored in the medium management storage means 1 with the storage area management table 11 of the storage area management means 2,
Which shelves store or do not store storage media, whether storage media is standard media or non-standard media, which shelves are available or which are unavailable Is determined, and each state is stored in the shelf state information 16 of the storage area state table 14. The processing is performed for all the shelves of the collective storage device to be replaced, and when the processing is completed, the control is transferred to the replacement means 6.

The replacement means 6 replaces the storage medium so as to match the information in the storage area management table 11 of the storage area management means 2. First, one shelf number information 13 and a pair of medium name information 12 are read. Thereafter, the storage medium contained in the shelf number stored in the shelf number information 13 is loaded into the read / write port of the collective storage device, and the medium name is checked. If the media name actually stored on the shelf matches the media name information 12,
The same shelf number information as the shelf number information 13 in the storage area status table 14
A value indicating that the replacement work has been completed is stored in the shelf state information 16 paired with 15. If the loaded medium name does not match the medium name information 12, if the loaded medium name is a standard medium, the medium name information 12 storing the medium name is stored in the storage area management table 11. If there is media name information 12 that matches, remove the storage medium on the shelf, store the currently mounted storage medium on the shelf, and pair with the shelf number information 15 that is the same as the shelf number. A value indicating that the replacement work has been completed is stored in the shelf state information 16 that is displayed.

Next, the storage area management table 11 is searched for the name of the storage medium removed to store the first storage medium, and if the same medium name information 12 as the medium name is found, the shelf number information 13 paired therewith is searched. The above processing is repeated based on the above. When the same medium name information 12 as the medium name is not found, the currently mounted storage medium is returned to the shelf from which the storage medium was first extracted, and the same shelf number information 15 as the initial shelf number information 13 and the same. A value indicating that a storage medium that does not match the information is stored in the paired shelf state information 16, and the repetition processing for one piece of shelf number information 13 ends.

Also, if the loaded storage medium is a non-standard medium,
When the medium name information 12 is a medium name for a non-standard medium,
The shelf status information 16 that is paired with the shelf number information 15 that is the same as the shelf number information 13 stores a value indicating that the replacement operation is to be completed, and if the medium name information 12 is not a medium name for a non-standard medium, The shelf status information 16 paired with the same shelf number information 15 as the number information 13 stores a value indicating that a storage medium that does not match the information is stored, and one shelf number information 13
The repetition processing for the operation ends.

When the repetition processing for this one storage area management table 11 is completed, the processing for the next storage area management table 11 is performed. However, in the second and subsequent processes, before the repetition process is performed, the storage medium that matches the shelf state information 16 paired with the same shelf number information 15 as the shelf number information 13 is stored. When the value is stored, or when the value indicating that the replacement work has been completed is stored, the process for the storage area management table 11 is passed and the processing for the next storage area management table 11 is performed.

This series of processes is performed for the tables existing in the storage area management table 11, and after the processing is completed, the storage area management storage unit 2 is stored in the shelf state information 16 of the storage area state table 14.
If a value indicating that the information of the storage medium does not match the information of the actual storage medium is stored, all shelf number information 15 paired with the shelf state information having that value is reported as an execution result. Thus, the storage medium replacement method ends the processing.
