Most of the commercial/industrial tape cassette drives of the 70s and
80s used standard saturation recording, not audio recording. I
remember a dual-deck Techtran drive that I was very fond of. It could
run up to 9600 bps and do searches as well as tape-to-tape copying.
I'm occasionally contacted by folks with old EDM rigs, like the
Mitsubishi DWC-90H, looking for help. Those took an external cassette
drive. Fortunately, there's an outfit that offers a PC-based solution
to supply the tape deck functionality.
For a time, cassette decks were used as a substitute for punched paper
tape in the commercial embroidery business They were supplanted by
floppy drive boxes, eventually (e.g. Barudan).
