Tape drive storage device for writing data forward and backward in predetermined lengths
A data storage device for writing data. When data is written to tape, a predetermined length of tape is allocated on a first track for the data. The data is forward written on a first track and reverse written, in the same sequence, on a second track on the tape. If the data cannot be written on the predetermined length of tape, then a linking writer writes the data in a length unrestricted on the tape, and the predetermined length of tape is adjusted for the next data to be written to the tape.
