I believe that what you just described is a mono VCR and stereo non-HiFi
VCR. HiFi VCRs have two sets of audio heads, one that reads the old
style signal along the edge of the tape, and one that reads it from
across the entire tape. The later set provide higher quality, but don't
allow one to write audio without stompiong on whatever video may be
there. There for, pros used to not use it (although I'd imagine they
use it again now that non-linear editing is the standard and they'd be
unlikely to want to write the audio and video seperately I'd think).
I suppose some consumer "hifi" VCRs might play hifi, but not record it.
That would stink. But Hifi does use the entire tape.

Who inserts an analog step between the CD and MP3 anymore? Maybe some
lamers did when MP3s first arrived, but the cool cats have always used
I'm a fan of keeping it digital once it is digital until it hits the
speakers, but I do like analog tape somewhat, and analog mixers. Or
analog mixers and digital tape is also nice. But all of that is
expensive to do well, while good digital can be extremely cheap.
