A storage device is connected to a tape library having a plurality of tapes holding data and a host device. The storage device includes a receiving section, a first determining section and a reading section. The receiving section receives a request for data held in one of the tapes from the host device. The first determining section determines whether the data requested by the host device is stored in a storage section on the basis of the request received by the receiving section. The reading section reads the data in a predetermined amount to a memory from the tape in a case where the first determining section determines that the data is not stored in the storage section. The transferring section transfers the data in the memory to the host device and writes it on the storage section. |
