Buffering can increase the performance of a write operation
when no errors occur. Values can be:

unknown.
RECORD No buffering is performed on tape writes
(every record written to the tape process is
passed to the tape drive immediately).
FILE File buffering is performed on tape writes
(records are passed to the tape drive only
when a file mark is written). This means
that an application might have to rewrite all
records written since the last file mark if an
unrecoverable error occurs during a write
to tape.
