On a related subject, Sony had a system called PCM-1630 that stored digital audio data as an RS-170 (B&W 525/30) video signal which was recorded on modified U-Matic VCR’s. The bandwidth was 1.5 Mbps after error correction to be able to record 44.1KHz sample rate 16 bit stereo audio. 
The system was pretty reliable since almost EVERY CD made between 1982 and 1997-98 used that system for mastering: 

There was also a consumer version called PCM-F1 which recorded 44.056/14 audio on consumer Betamax.
