Patent ID: 8035912

Claim:
A system for controlling the traveling of a tape in a tape drive which temporarily stores data in a buffer before writing the data to the tape, the system comprising: a determination unit for determining if second data is to be written to the tape without performing a backhitch after first data is written to the tape, the determination unit determining a state of the system before writing the first data to the tape, the determination unit comparing an amount of second data written to the tape with an amount of second data expected to be written to the tape to an area up to a position on the tape where writing the first data commenced, for determining if the second data is to be written to the tape without performing a backhitch, the second data comprising data stored adjacent to first data stored in the buffer; and a speed adjusting unit for adjusting the speed of the tape to prevent a backhitch due to the buffer running out of data when the determination unit determines that the second data is to be written to the tape without performing a backhitch.
