Thanks Chip! I think you are right based on this description I found of a cutter head:"Stereo is made up of a left signal and a right signal. OK, that's simple. But stereo can also be described as the "mono component" (everything that is exactly the same in both speakers) and the "difference component" (everything that is different). This is commonly called Middle and Side, or M-S for short.
It can be hard to believe because we commonly think in "left and right" rather than "middle and side". But it's true. It's a matter of physics and alternating current electronics.
The groove shows us the difference signal by it's depth. So a mastering engineer says "lateral" and means the mono (or middle) signal. And when the engineer says "vertical" he or she is referring to the difference (or side) signals."Gerry
