Actually shouldn't the list read more like:

TK50 CompacTape 95MB 350 o
TK70 CompacTape II 270MB 350 o
TK?? CompacTape III (DLT) 20GB/40GB 1540 o
TK87 CompacTape IV (DLT) 35GB/70GB 1850 o

A III or IV can be used in both DLT4000 and DLT7000 drives, I think the
DLT2000 uses III's and the DLT8000 (Least I think that's the new drives
designation) use IV's (not sure if they can use III's).

There are also some other versions of drives, and I believe tapes. IIIe
and IIIxt come to mind.

In case anyone cares, a DLT7000 is about a $5000.00 drive and according to
specs stores 35GB uncompressed, 70GB compressed (I've seen WELL over 100GB
on a single tape).
