PROBLEM TO BE SOLVED: To solve a following problem: data written in an ABF lap cannot be read out by being overwritten by the other data written in the ABF lap or data written in a normal lap. SOLUTION: In a controller 16 of a tape drive, a buffer managing part 42 detects the occurrence of flash, a channel input/output part 43 writes first data in a ABF lap of a normal direction at the occurrence of flash through a write-in head, and writes second data in a second ABF lap of the reverse direction at the occurrence of flash, after that, the part 43 writes first data and second data in a first normal lap of a normal direction adjacent to the first ABF lap. Among them, when the second data is written in the second ABF lap, an offset discriminating part 44 controls the write-in head so that the write-in head is offset to a direction of a second normal lap of a reverse direction used next to the first normal lap.
