    摘要: In one embodiment, a method includes writing a file into a data partition of a tape medium, writing a pointer of the written file in an index partition and creating a high resolution tape directory (HRTD) including detailed location information of data in a data partition. The method also includes storing the HRTD as part of end of data (EOD) of the index partition in response to a tape cartridge housing the tape medium being unloaded. The storing the HRTD as part of the EOD of the index partition includes requesting movement of the tape medium to the index partition in order to update an index file after changes have occurred to data in the data partition, writing an updated index file into the index partition concurrent to writing an updated HRTD into the EOD of the index partition, and requesting for the tape cartridge to be unloaded.

    摘要: In one general embodiment, a method includes receiving a request for a write operation to be performed in a tape drive; determining a capacity margin ratio of the tape drive; determining an optimum a write procedure based at least in part on the capacity margin ratio; and invoking the optimum write procedure in response to determining the optimum write procedure. The optimum write procedure is selected from the group consisting of: a backhitch write procedure, a same wrap backhitchless flush (SWBF) write procedure, and a recursively accumulating backhitchless flush (RABF) write procedure. Systems and computer program products configured to perform similar techniques are also disclosed.

    摘要: Data is recorded such that the positions of data will be aligned in a traveling direction and a width direction of the storage medium. The medium travels in the traveling direction from a first to a second position as a certain wrap of a group of plural files in a first physical range between the first and the second positions. A head shifts from the certain wrap to another wrap in the width direction of the medium. The medium travels in the traveling direction from a third to a fourth position as the other wrap of a group of plural files in a second physical range between the third and the fourth positions. The plural files in groups on the certain wrap and the other wrap may be written in reverse order to each other after being once stored in a buffer.
