ABSTRACT:
A storage media library device includes a media drive unit which writes and reads information on storage media, a media storage unit which stores the storage media, a robot which transports the storage media between the media drive unit and the media storage unit, a robot control unit which controls the storage media transport operation of the robot, and a vibration detection unit which detects occurrence of vibrations. The robot control unit is controlled by a library control unit, wherein if occurrence of vibrations is detected by the vibration detection unit during the robot transports the storage media, the robot control unit causes the robot to stop the storage media transport operation, and when subsidence of the vibrations is detected within a predefined time period preset in a storage media transport command and monitored by the library control unit, the robot control unit causes the robot to resume.
