Abstract

Various systems and methods are presented regarding interrupting a write operation to enable a read operation to be performed on a digital tape system. An initial write operation to the tape can be paused, a read operation performed on a previously written data file conducted, and upon completion of the read operation, the write operation can be recommenced. Interrupt points can be positioned within respective data blocks. Based upon knowledge of the amount of data written during the initial write operation, a position P can be determined (relative to the location of the nearest prior interrupt point) such that when the tape is advanced to place the tape head in a position to recommence the write operation after the read operation has been performed, the tape can be positioned such that the tape head is at position P. Accordingly, interruption of the write operation enables random access of the tape.
