Back in the late '60s I remember seeing a unit
from IBM that
used film storage. The film was a small rectangle, maybe 1" x
2-1/2". These were stored in magazines of some sort, IIRC.
They could be individually selected randomly.
I have one of the film rectangles somewhere. When I run
across it again I will post a link to an image. In the mean
time, does this ring a bell with anyone?
Aperture cards. An IBM punch card with a square of film in it. The punch
coding was a filing system serial number. There were variations that
looked like 35mm slides with a bigger than normal cardboard mount too.
I used to work for the Terminal Data Corp, and along with Kodak we made
90% of the microfiche/microfilm cameras in the American market. Many
other manufacturers, esp. COM systems (Computer Output to Microfilm)
used our cameras.

Think of Emmanuel Goldberg's "Rapid Selector",
and Vannevar Bush's Memex copy of it.
(movie film microfilm, with binary optical filing data alongside)

Thanks for the extremely obscure but highly informative reference to
Emmanuel Goldberg! I didn't know about this.

OBSCURE???
^^^^^^^^
Michael Buckland was my PhD advisor. Very interesting chap.
try also:
http://www.sims.berkeley.edu/~buckland/goldbush.html
I did some trivial research for Buckalnd, including checking my 50 to 70
year old photography books to confirm that Bush's gate-less projector
could not have been produced with available materials at the time:
proof-of-concept, but NOT functional. (Calculate what speed the flash
tube would have to have been to provide an unblurred image of microfilm
moving past.)
Goldberg was chief engineer at Zeiss. But, because he was Jewish,
during WW2, Zeiss systematically deleted all reference to his existence.
In the body (not online) of:
http://www.sims.berkeley.edu/research/projects/oasis/trade.html
I am given credit as the father of "perverse" retrieval, for
pointing out that use of "best possible" retrieval as a constraint
for results also calls for identifying "worst possible" as the
opposite boundary.

Nope. I know what an aperture card is. This was something entirely
different. The little piece of film has some hole at one end to shove
(pull?) it around with. The other writer was correct. The little cases the
things were in vaguely resembled the little cases you might see a whole
bunch of single edge razor blades in. The reader would pull the right
cartridge, then pull the right film, then read the patterns. There was no
paper attached to this and the file did not contain an image like an
aperture card does. It was data stored in a black and white pattern on the
film
