ABSTRACT:
A storage device system comprises interfaces connected to computers, a plurality of magnetic disks, and a control device that controls the plurality of magnetic disks. When a command from one of the computers instructing a tape library device to load a magnetic tape into a tape device is received by one of the interfaces, the control device selects a storage region that is managed as a virtual tape from among storage regions of the magnetic disks. When one of the interfaces receives an access request from the computer to the tape device, the control device controls to access the storage region selected.
