Abstract
Reuse of partially expired physical tape volumes reuse is attained in a longitudinal tape data storage drive, wherein data is stored as a sequence of serpentine wraps, a wrap comprising a first linear path traced on a longitudinal tape; and another linear path, laterally spaced from the first linear path, traced on the longitudinal tape; the linear paths extending from one end of the longitudinal tape to the opposite end and arranged in opposite directions. One embodiment of a method comprises identifying expired portions of stored data on the longitudinal tape; determining whether data of a complete linear path of the longitudinal tape has been expired; and allowing reuse of any determined complete linear path for storage of data.
