ABSTRACT:
Radio tags storing parts identifying information are arranged for the individual constituent modules such as tape drives and conveying robots of the library apparatus. Upon every rise of the apparatus, the conveying robots are moved to positions permitting read of the radio tags arranged on the individual constituent modules. The parts identifying information such as the serial number is read by the tag reader and stored in the non-volatile memory. When this is different from the serial number read in the preceding run, stored in the non-volatile memory, it is determined that the part has been replaced. The statistical information of the number of operating runs is then cleared, and management of the parts service life is started.
