I recall a Logabax computer (a french office / accounting system that seems
to e completely forgotten) in about 1975 that had a built-in mechanism that
used audio cassettes. The tapes, if played on an audio system, were a
series of tones not unlike CUTS - I guess the idea of recording as audio
something intended to be sent over the telephone system was fairly obvious.

working on a project, and I need to know the age of various tape
formats. For example when were 6250bpi 700’ 9-Track tapes or DC600A
cartridges introduced? Is there any good resource online that
documents this? Wikipedia is of some help, but the older you go, the
spottier it is.
For QIC,
qic.org has a some info. For DLT and LTO, the wikipedia pages
are fairly useful.
What about the data cassettes used on things like Plato? Not at all
like the
audio cassettes later used on home computers.
