ABSTRACT:
A sequential buffer for a magnetic tape data storage system comprises a plurality of segments. A buffer management system buffers data in the sequential buffer, conducting a data transfer process. Subsequently, some of the buffered data is maintained in some, but less than all, the segments of the buffer. Additionally, the maintained buffered data is indicated as VALID data. Thus, a subsequent process may be conducted directly using the data maintained in the buffer, and avoids moving the tape to reread the data.
