DATA WRITING METHOD IN TAPE DRIVE, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To improve a data transfer speed during reading by a new data writing method to a tape.SOLUTION: A tape drive for recording data while making a tape reciprocatingly running includes (a) a step for storing data received from each of at least two data sources or more in a buffer, (b) a step for writing the data received from each of the two data sources or more and stored in the buffer in a specific area of a lap in each data source at predetermined length of the first lap in a predetermined order, and (c) a step for moving a head to a second lap of the tape when arriving at an end edge of a first lap of the tape, and writing data of each data source in a specific area of the lap in each data source at predetermined length of the second lap in an inverse order of the predetermined order of the first lap while making the tape running in the opposite direction from the writing to the first lap.
