NOTES:
1.
The suggested values of
density setting #1 and #2 are for compressed and
uncompressed format respectively. The only use of uncompressed format is if the
data is already compressed.
2.
The
density value can be useful in reading tapes on earlier TK85, TZ86, TZ87, and
TZ88 cartridges.
3.
Compaq recommends changing the block size of the TZ89 DLT Cartridge SBB Tape
Drive or Tabletop Tape Drive to the maximum allowed by the operating system,
utility, or application. However, for some uses such as making bootable tapes or
transferring tapes between host systems, a value of 512 or 0 (variable size) may be
needed.
