    摘要： In a magnetic recording and/or reproducing apparatus applied to an external storage of computers, a recorded file can be searched easily. A recording track is helically formed on a magnetic tape to record file data, and management data are recorded at the beginning of the magnetic tape, and a search pattern is recorded on the recording track along the longitudinal direction at a location of the magnetic tape that corresponds to the management data of the beginning of the magnetic tape.

    摘要： A virtual library apparatus includes an exclusive control section that exclusively secures a logical drive and a physical drive according to an instruction from a host at a time of an occurrence of an error in the physical drive and a diagnostic section that performs a diagnostic process on the exclusively secured physical drive through the exclusively secured logical drive. The exclusive control section releases the exclusively secured logical and physical drives after the diagnostic section completes the diagnostic process for the physical drive.

    摘要： A tape operation relating to EOF identification in an open process for a file is emulated, whereby the tape operation in the open process is simplified. Consequently, open-process, close-process performance, and process performance of a system accessing to a magnetic tape unit can be improved. In a method of this invention, a position of a head relative to a magnetic tape is fixed at a predetermined position in the open process for a file recorded on the magnetic tape, and when a command is received from a command issuing apparatus, emulation in which a tape operation according the command is virtually carried out in the magnetic tape unit without making said magnetic tape unit carry out a real tape operation, is executed.

    摘要： The present invention relates to a magnetic tape unit to which a cartridge having a magnetic tape therein is detachably attached and which accesses a magnetic tape in accordance with an access request from a host. Software of the host which accesses a conventional magnetic tape unit to which a cartridge accommodating a plurality of cartridges is attached is used as it is while using the cartridge accommodating a large-capacity magnetic tape. Management information of a plurality of volumes is written in the cartridge, and a LOAD command from the host is replaced by a command for accessing an actual cartridge.
