    Abstract: PROBLEM TO BE SOLVED: To improve write performance to a tape medium while securing resistance to errors.SOLUTION: In a controller 16 for a tape drive, a CM input/output part 44 recognizes a tape format, a tape variable acquisition part 45 acquires a tape variable corresponding to the tape format, a set variable acquisition part 46 acquires a set variable, a minimum number calculation part 47 uses the tape variable and the set variable to calculate a minimum number m of a sub-data set to write so as to secure resistance to a burst error. When a command processing part 41 receives a synchronous command, a buffer management part 42 generates an n pieces of sub-data set for storing data in the buffer, when n is smaller than m, padding is performed to make m pieces of sub-data set write data, and when n is equal to or larger than m, n pieces of sub-data set is made the write data, and a channel input/output part 43 writes the write data to the tape.

    Abstract: PROBLEM TO BE SOLVED: To perform access not lowering a performance specialized in sequential media without executing mounting depending on a hardware device on an application side.SOLUTION: In a file system 60, a command processing part 61 takes out an option indicating a file listing method from a command, an index reception part 63 receives an index including a directory name, a file name and a recording position from a tape drive, and an index storage part 66 stores the index in the state as it is or in the state of changing the directory name or the file name according to the listing method indicated by the option. In the meantime, when an IRP reception part 67 receives an IRP (I/O Request Packet) from an OS, an IRP setting part 68 stores the file name inside the index in a buffer of the IRP in the order of the recording position, and a response transmission part 69 returns a status to the OS.

    Abstract: The invention provides a method that detects whether data on a tape drive used in a file system has been altered. The method contains: (a) a step that prepares a first tape cartridge provided with a tape in which multiple files and an index information history have been stored in a WORM partition, and index information has been stored in an R/W partition; (b) a step that reads and compares the R/W partition index information and the index information at the end of the WORM partition; and (c) a step that determines that the R/W partition index information has been altered if the R/W partition index information does not match the index information at the end of the WORM partition.

    Abstract: Disclosed is a tape writing method for small transactions. For a data set of fixed length, (step 1) a first file is written as a plurality of DSs, and the DS number and the WP number of the last DS are stored into memory as #N (DS#N) and #M (WP#M), respectively; and (step 2) into the DS which follows the last DS (DS#N, WP#M) that includes the first file, the last first and second files are packed and sequentially written in units of DSs, and into the DS which includes the second file, DS#N, DS#N+1, ¦, and WP#M+1 are sequentially stored into memory. (Step 3) The remainder of the first, second, and third files are packed, and with DS#N at WP#M+2, the DS#N of WP#M is appended onto, and for after the DS number of the second and third files, the remaining portion of the #N is written as following DSs as DS#N+1, DS#N+2, ¦, at WP#M+2. With DS#N, #N+1, #N+2, ¦, the WP#M+2 is stored into memory.
