Really?
I actually *do* have a 9 track tape drive (HP 7970)
that has 200/556/800
bpi densities:
And it is a *9* track tape, I know for sure.
Actually, what you have is a *dual-density* tape drive, an HP7970E. It
will write 9-track tapes at 800bpi, or 7-track tapes at 200, 556, or 800.
See the manual for the 7970 drive family at
