I think I have a pretty solid understanding of how hifi stereo
is recorded on VHS tape. However, I'm unsure about the details of
linear stereo. I would guess (from the name "linear") that the left
and right audio are recorded at the sides of the tape outside of the
video area, right? The left/mono channel on one side of the tape, the
right channel on the other? Do current pre-recorded tapes contain the
linear stereo recording or just mono and hifi? Do current hifi vcrs
record in linear stereo, or again is it only mono on the linear track(s)?
The reason I ask this is that some pre-recorded tapes explicity state
that they include linear stereo whereas others do not make this
distinction. As I understand it, no consumer vcrs in the last four
years have been linear stereo only; just hifi or mono.

Thanks for any information you can provide.

Linear stereo splits the existing mono track in half with a guard band to achieve 2 channel sound, and is a poor man's bargain basement stereo sound system. Recorded at slower speed of the mono track, it's fairly hissy and noisy and requires a noise
reduction system to improve the audio quality and this is usually the Dolby B NR system which some linear stereo decks have, but for all it's prowess if rather poor, the sound takes an appreciable dive in LP and SLP / ELP modes and sounds horrible.

The HiFi VHS Stereo system developed by JVC (and adopted by many manufacturers), sounds much much better as it is multiplex depth recorded in the vision portion of the video recording layer and is clearer and more expansive with better fidelity of the
recorded audio and crystal clear trebles.
