lansingxcore said:i'm glad somebody takes the time to answer perfectly reasonable questions instead of just taking cheap jabs.. the guy was obviously asking about analog recording to that format (since this is the analog only forum), and i have wondered that myself.. thanks ghost, now we know.
if you don't have something nice to say...
Standard VCR's at SP, run at 1,7/8ips; the same speed as a standard home cassette deck and if you've ever heard the quality,(or lack there-of) of the linear soundtrack on a VCR you'll know pretty quickly why the analog multitrack VCR never caught on.
Keep in mind too that video tape is a completely different formulation that is optimized to recording video only in a helical scanning system that speeds up the writing speed to capture video frequencies which are in the megahertz.
Audio recorders need tape that is optimized and designed for the frequency's range in kilohertz and as cheap and plentiful as blank video cassettes are its like being in the desert and being surrounded by miles of free sand when all you really needed is a glass of water.

If you are talking about the hi-fi audio tracks, those are not the analog linear tracks. That audio is encoded with the video signal and will suffer from the same tracking problems that will make the top of the piture scew, etc... It is captured at the same 29 some odd frames per second that the video is.
The linear audio tracks are the ones you hear on a non hi-fi vcr and when the tracking is off on a hi-fi vcr. You know, the lifeless muddy sounding ones.
Now that's something to be proud of!it went on to become one of the more hostile threads for the analog section
The bottom line is, if the audio quality meets your needs, then it works for you.But if this was the case, that the tape itself isn't built for audio, then how are we getting good quality from the 2 audio tracks that are there?
Read it again. The audio is written by the spinning head in helical stripes. That means that the tracking has to be dead on in order for it to be even read. Normal analog tape records the signal in a straight line along the length of the tape, not in little stripes 30 time a second.Hmm. Per the wiki entry, it looks like the audio is laid down just like on any other analog tape:
Around 1985, HiFi VCRs emerged, adding higher-quality stereo audio tracks (20 Hz to 20 kHz with more than 70 dB S/N ratio) which are read and written by heads located on the same spinning drum that carries the video heads with frequency modulation. These audio tracks take advantage of depth multiplexing: since they use lower frequencies than the video, their magnetization signals penetrate deeper into the tape. When the video signal is written by the following video head, it erases and overwrites the audio signal at the surface of the tape, but leaves the deeper portion of the signal undisturbed. (PAL versions of Betamax use this same technique.)
What is LOE?So answer the question above.
OK, let me throw this out there:
What kind of LOE for the development of a multi-track tape head would some of you estimate?
"Read it again. The audio is written by the spinning head in helical stripes."
I could have read it a thousand times and it wouldn't matter. I'm just not as smart as you.
So answer the question above.
What is LOE?
This is something I looked into back when I was an audio/video mastering engineer. We were thinking if you substituted the 2 video heads for FMA heads and increased the tape speed, you could get 4 tracks. But tracking would be crucial. Things track better at higher speeds.
But there really isn't any advantage of the hi-fi over a good analog tape machine. We made bin loop masters for cassette duplication on 4 track 1/2" tape and that had better specs than the hi-fi.
The one advantage to hi-fi VHS is convenience. 2 hrs in a cassette vs dealing with open reel.
In the early days we had a sony pcm f1 converter and stored digital audio on vhs tapes.
...and it went on to become one of the more hostile threads for the analog section.
