摘要： A tape apparatus increases throughput of data access requests by rearranging the sequence in which data access requests are processed in order to reduce repositioning of a tape medium. The tape apparatus includes a command queue for storing a plurality of instructions from a host apparatus, and a reordering mechanism for analyzing the stored instructions according to a predetermined set of rules. The sequence of the stored instructions are rearranged in order to minimize driving of the tape medium. The reordering mechanism can select N commands at a time from the head of the command queue, and determine a sequence for executing the N commands, yielding a minimum total driving distance of a medium tape from a current position of the tape medium.

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 header data storage unit stores therein header data that identifies each file. A header data reader reads the stored header data, from the header data of the first file written to a magnetic tape to the header data of a target file, in order in which the files have been written to the magnetic tape. Based on the number of files whose header data have been read, an input/output controller controls positioning of a magnetic head.

摘要： A library system in which a recording and reproducing unit loads a recording medium after an accessor has retired from the recording and reproducing unit by exchanging data between the recording and reproducing unit and the accessor on the occasion that the recording and reproducing unit loads a recording medium carried from the accessor to the recording and reproducing unit. Moreover, the library system has an object to realize communication of the necessary data between the recording reproducing unit and accessor without increase of a load of the director for controlling the recording and reproducing unit and accessor. The library system has a store house (51) for storing a large number of recording medium, a recording and reproducing limit (52) for realizing read and write operation to a recording medium, an accessor (53) for transferring recording medium between the store house (51) and recording and reproducing unit (52) and a director (54) for controlling the library system (20) as a whole including the recording and reproducing unit (52) and accessor (53) and moreover a third communication means (55) for transmitting instructions between the recording and reproducing unit (52) and accessor (53).

摘要： A library apparatus where multiple moving commands generated by several upper-order units are conveyed to a director. The moving commands may be sequentially conveyed through the same channel or may be simultaneously conveyed through different channels. The moving commands are then conveyed to an accessor controller which includes a queuing table for storing the commands. The queuing table permits the accessor controller to receive additional commands prior to the execution of the previous command. Therefore, the processing speed of the system is increased. Next, the commands are conveyed to a plurality of accessors which transfer the medium cartridges to the desired location. Several accessors may be operated simultaneously in parallel. The simultaneous operation of several accessors also increases the efficiency and speed of the system.

摘要： A storage apparatus includes a storage drive which writes and reads out a block of data with respect to a storage medium loaded on the storage apparatus, a processor which executes access control on a plurality of volumes assigned to the storage medium and a memory which stores a piece of management information that includes a piece of information indicating a usage frequency of each of the volumes. The processor executes a procedure including: determining a reallocation target volume from among a plurality of volumes assigned to the storage medium based on the management information, and moving the data of the reallocation target volume to a reallocation destination storage medium which is different from the storage medium.
