Note a: The logical position is located on the EOM side of the mark if movement was in the forward direction and on
the BOM side of the mark if movement was in the reverse direction.
Note b: The Information field is set to the difference (residue) between the requested count and the actual number of
blocks, file marks, Set-marks, or spaced over.
Note c: The Information field will contain no residue count and therefore the Valid bit is not set.
Note d: The drive will only report that a Set-mark has been detected while spacing over blocks or File marks, if it has
been configured through MODE SELECT to Report Set-marks. Otherwise, the drive will continue the space
operation and the presence of the Set-mark will be transparent to the Host.
Note e: The tape is positioned such that a subsequent WRITE would append data after the last entity that has been
written to the tape before EOD.
Note f: The tape is physically positioned at BOM/P.
Note g: EOM is only reported when the physical EOM/P is encountered. The tape is physically positioned at EOM/P.
