There were 2 failed early (late 1950s, early 1960s) attempts at domestic video recorders, Wesgrove and Telcan. Both used high speed linear recording. I think there was a Fisher Price or similar toy video recorder that used high speed linear recording, possibly on a standard audio cassette.
BBC Research made an experimental linear scan digital VTR in the early 1970s. It used an instrumentation recorder (1"?) runnng at high speed. I saw it running in 1974/5. AFAIK it was purely a research tool for investigating digital TV systems.
Going the other way, digital audio was recorded on both Umatic and Betamax video recorders. The digital audio was processed to make it look like analogue video. Both were successfully employed by major recording companies. They could outperform any analogue audio tape recorder. Their performance was limited only by the quality of the ADC and DAC.
PS: Here's the Fisher Price camcorder: https://en.wikipedia.org/wiki/PXL-2000 Apparently it now has a cult following.
