I just rec'd my copy of Electronic Musician. (10/86). There's an article
on stereo mastering using Beta HIFI in the Home studio.
You all certainly are hip to the advantages of VCR's in general
for low bux hiquality audio. There is a picture in there depicting
the general track layout of BETA :
--------------------------------- conventional audio track
/ / / / / / / / / / / / / / / / /
/ / / / / / / / / / / / / / / / video trax (w/ stereo hifi audio)
/ / / / / / / / / / / / / / / /
--------------------------------- conventional audio track
In the text, it states that: "the helical-scan rotating heads used for
video can also record the BHF audio signal on tape.... with an effective
tape speed of 270 i.p.s. [!!!]... the audio input feeds the conventional
audio and BHF heads SIMULTANEOUSLY (my emphasis)... However, on some
machines you can THEN (later??) record a different signal
onto the conventional audio tracks...you can stripe SMPTE...you wind
up with a high quality stereo master with a SMPTE sync track..."
Well. My question is this: If one were limited on tape channels and
was compelled to do the stereo dump/intermix rag, could one create a
THREE-CHANNEL intermix, fully intending to xfer it back to multitrack,
normal BETA stereo on the music, while carrying along, with no temporal
displacement, the FSK (or whatever format) SYNC track?

Karl,
I have a VHS HiFi Deck, but I believe that you cannot SIMULTANEOUSLY
record three different signals on any of the HiFi Video Decks. What
the article is probably suggesting is a later dub onto the LoFi
channels. I must confess that although I subscribe to Electronic Musician,
I haven't read the article yet.

Karl,
I have a Sony SLHF-900 super beta hi-fi deck. I bought it with
similar thoughts in mind. I also intended to get a unit
to master digitally, until I found out that digital edits aren't
possible.
Yes you can record on three independant tracks at one time (on this
deck). Or you can dub the linear or hi-fi track in separately.
Monitoring may be a problem, as you can listen to hi-fi, the linear,
or both, via the stereo output jacks, but not separate them.
I believe that it would be a minor task to tap the monitor select
switch and thus separate them on output, though.
The beta hi-fi sound quality on this model is superior to the
hi-fi on other decks (my opinion). Some have modulation noise.
And note the hi-fi tracks are frequency modulated versus straight
conventional recording.
