To the best of my knowledge, this is not correct. VHS has little or no gap
between the stripes, nor does Betamax. That's what "Betamax" refers to --
maximum surface coverage, "bet" being the Japanese word for surface
coverage.

Because the luminance signal is FM, a bit of leakage causes no harm, as the
FM
capture effect can be used to eliminate it, by limiting the signal. The
chrominance signal is AM, and an alternating- or rotating-phase carrier is
used to minimize crosstalk.



Well, I might have to do a bit of Googling then, I've never been involved
much with video.

The main difference is, I believe, that DAT kind of reads 3 tracks at once,
video doesn't, thus head size is critical if considering some kind of head
substitution.
