Write - IBM Ultrium Internal Tape Drive T200 Reference Manual

WRITE

The WRITE command causes data to be transferred to the drive in a Data Out and
written to tape.
If the Fixed flag is clear, the initiator transfers a single block of the length indicated
in Transfer Length.
If the Fixed flag is set, the initiator transfers a sequence of blocks. The number of
blocks is given by the Transfer Length field. The length of the blocks is given by the
current fixed block length (see "Mode Block Descriptor" on page 29).
If the current logical block number is greater than FFFFFF00h and less than
FFFFFFF0h, rules for Logical EOM processing are applied. If the current logical
block number is FFFFFFF0h, rules for physical end of tape processing are applied.
