Was going through all my HP paper tapes to inventory them and came across
the following mini-cart cartridge tapes (the kind you use in a 264x
terminal, DC100 I think). Unfortunately it is an obviously incomplete set,
but thought I'd list it here in case anyone is desperate for one of them.
They are all original HP labels.
RTE II + III + IV, MINI-CART (PE), #1 (C) rev 1840
RTE II ONLY, MINI-CART (PE), #2 (C) rev 1840
DG 1000 CRTG #1*, MINI-CART PE FMGR, 24998-13301 (C) REV 2326
DG 1000 CRTG #2, MINI-CART PE FMGR, 24998-13302 (C) REV 1926
DG 1000 CRTG #5, MINI-CART PE FMGR, 24998-13305 (C) REV 1822

Even if someone was desperate for any of those tapes, what are the
chances they would still be readable at this point and there wouldn't
be spots where the oxide has flaked off?
I gave up after trying to read a couple of HP1000 diag tapes on 264x
media quite a while ago. But that's ok since you're going to have a
complete set of HP1000 diags available real soon now, and I can wait
until then. :-)

It would probably be best to go through a bake cycle, that's for sure.
I know Al and a few other people have setups for digitizing the analog
outputs of the read heads for 7-track and 9-track magtapes, but has
anyone concocted a similar beast for the DC100 or QIC tapes?
Is it even possible?

The chances are very good because HP used good tapes (I know of
experience). I was able to rescue every HP tape I have.

No! Don't bake them (it's unnecessary anyway because the tape itself
doesn't stick). BUT: You need to unstick the belt from the tape. Open the
cartridge and slightly heat the belt until it is black again (sticky belts
mostly have a white coating that will vanish when heated). I put these
tapes under a desk lamp with a distance of about 20cm (depends on the
power of the light bulb) and then wait a couple of minutes while watching
the tape.
In my experience the biggest problem is the belt. Many of these belts will
tear after some time, and finding a replacement belt is difficult. I don't
know (haven't tried yet) if a belt from a DC2120 (QIC80) or similar
cartridge (those cartridges are easy to find today) can be used.
