Abstract:
1. A storage media library device comprising a media drive unit which writes and reads information on a plurality of storage media, a media storage unit which stores said storage media in a media storage rack, a robot which is operated to transport said storage media between said media drive unit and said media storage unit, an identification code/relative position detection unit which detects an identification code attached to each of said storage media and also detects relative positions of said robot with respect to said media drive unit and said media storage unit, and a robot control unit which controls the storage media transport operation of said robot based on said identification code and said relative positions detected by said identification code/relative position detection unit, wherein said storage media library device comprises a vibration detection unit which detects occurrence of vibrations, and said storage media library device is connected to a host computer having a library control unit which controls various operations of said media drive unit and said robot control unit, and wherein when said robot is performing said storage media transport operation, if occurrence of vibrations is detected by said vibration detection unit, said robot control unit causes said robot to temporarily stop said storage media transport operation and puts said robot in a standby state, and when said vibration detection unit has detected that the vibrations have subsided within a predefined time period preset in a storage media transport command and monitored by said library control unit, said robot control unit causes said robot to resume said storage media transport operation.
