The factory programmed value is 00h (Default Density)

compatible with all medium types. See table 1-1 for an
overview. See also Table 30-2 for more specific details.
The Density Code field should be set 7Fh (No change)
unless a specific density is desired (this is especially
useful when a combination of a MODE SENSE and a MODE
SELECT command

density code).
When a Default Density code has been selected (00h), the

Table 14-8 shows the selected density (tape format) for
the various types of media (cartridge types).
A MODE SELECT command changing the density code may be
executed at any time. Note, however, that a change of
