Library apparatus, control method and program

A control method of a library apparatus comprising, as constituent modules, a medium depot keeping storage media in units of cells in a plurality of keeping cells;

• a plurality of recording/regenerating devices which record and regenerate information by the use of said storage media;
• medium conveyors which convey storage media between said medium depot and said recording/regenerating devices;
• and a controller which enters the storage medium taken out from said medium depot into said recording/regenerating device under the control of said medium conveyor based on a command from a host to cause said recording/regenerating device to record or regenerate the same;
• and further comprising radio tags arranged for the individual constituent modules maintained and replaced, and storing parts identifying information intrinsic to the individual constituent modules;
• and a tag reader mounted on said medium conveyor and reading the parts identifying information stored in said radio tags;
• said control method comprises:
• a parts replacement determining step of moving, for every rise of the apparatus, said medium conveyor to a position permitting read of said radio tags arranged for the individual constituent modules to read the parts identifying information by means of said tag reader and store the information in a non-volatile memory, and when the read information is different from the parts identifying information read in the preceding run stored in said non-volatile memory, determining that the part has been replaced;
• and
• a parts managing step of managing the parts service life by obtaining statistical information such as the number of operating runs for each of said constituent modules, and when said parts replacement determining unit determines that the part has been replaced, starting a new run of management of the parts life by clearing the statistical information such as said number of operating runs.

A program which causes a computer serving as a controller for a library apparatus comprising, as constituent modules, a medium depot keeping storage media in units of cells in a plurality of keeping cells;

• a plurality of recording/regenerating devices which record and regenerate information by the use of said storage media;
• medium conveyors which convey storage media between said medium depot and said recording/regenerating devices;
• and a controller which enters the storage medium taken out from said medium depot into said recording/regenerating device under the control of said medium convey based on a command from a host to cause said recording/regenerating device to record or regenerate the same, to execute:
• a parts replacement determining step of moving for every rise of the apparatus, said medium conveyor to a position permitting read of said radio tags arranged for the individual constituent modules to read the parts identifying information by means of said tag reader and store the information in a non-volatile memory, and when the read information is different from the parts identifying information read in the preceding run stored in said non-volatile memory, determining that the part has been replaced;
• and
• a parts managing step of managing the parts service life by obtaining statistical information such as the number of operating runs for each of said constituent modules, and when said parts replacement determining unit determines that the part has been replaced, starting a new run of management of the parts life by clearing the statistical information such as said number of operating runs.
