Diagram need[edit]

This really needs a diagram. — Omegatron 16:07, 21 July 2006 (UTC)

You would think it would be easy to find patent images, but navigating their site is a pain. I've found a few that would be useful, though? — Omegatron 18:48, 21 July 2006 (UTC)

If somebody would like to create a diagram, here's a good starting point for a re-creation: [1]. Peter S. 19:06, 21 July 2006 (UTC)

There's also a few I found that show the azimuthal separation thing, but I don't know which ones are most typical for, say, VHS. I think the ones I found are some proprietary format with six bands per frame or something. Anyway, recreated images would be better than patent images with dimension markings and everything.

An animation would be even better.  :-) — Omegatron 19:21, 21 July 2006 (UTC)

OK I draw a very simple diagram. One more thing. Could someone please draw a simple arrow on a copy of this photo to point out the plane of head tilt in azimuth recording. The text-based description is not clear too me. --Kubanczyk 22:29, 3 April 2007 (UTC)
