As has been pointed out in private email (and probably
here once it turns up) TLZ04 (60m tapes) is before
the DDS nomenclature started, 90m is DDS1,
120m is DDS2, 125m is DDS3.

Typical off-by-one error :-) Sorry

Apart from that, still be careful what you put where.
The tape-wearing properties of >60m tapes in a TLZ04
(and presumably other drives designed for 60m tapes)
are real. The TLZ07 (120m tapes) manual suggests
that 120m tapes should not be put in a TLZ06 (90m tapes
drive). Not clear whether the TLZ06 would recognise
120m tapes as bad for it and refuse to use them or
happily wear its head out on them.

My drives always seem to protect themselves
by chewing all the tapes, so I've never managed to
dirty a head, never mind wear one out :-)
