Abstract
An optical disc library apparatus, on which plural optical discs and plural optical drives are mounted, has the ability to reduce the degradation of recording/reproduction capability owing to the variation of temperature. In the optical disc library apparatus, causes for the quality degradation of the optical discs are analyzed; temperature inside the optical disc library apparatus is measured in order to make recoveries in accordance with the causes; an inspection cycle for inspecting the optical discs is determined on the basis of the measured temperature; and the inspection of recording qualities of optical discs on which data have already been recorded and that are stored in the optical disc library apparatus is performed by the optical drives on the basis of the measured temperature.
