You might check out NCR's CRAM.
512 3x14" cards had to be pretty bulky.

IIRC, the card, after being selected, fell by gravity down a
channel until it met the spinning drum, where a vacuum held it to
the drum for reading and writing. To release, I think fingers
picked it off the drum and inertia shot it back up the return
channel and a solenoid-operated plate smacked it back onto the
pack, suspended by the eight " lazy-'D' " rods which were the
selection mechanism.

RCA had a very similar gadget called the RACE. There was
one on our Multics machine for a while. It's mentioned at
multicians.org (MIT had one too). As this article points
out, neither MIT nor we ever wrote a driver for it.

However, one of the GE CE's was much enamored of it,
and would put it through its paces every month or so, though
I don't think he played enough to explore its failure modes
(though they must have been much like the CRAM).
