Here is some info... http://electronics.howstuffworks.com/question487.htm

The stylus (needle) rides in a groove that is cut with the same signal/wave that you would see on a scope - the original waveform. The needle/stylus generates a signal between coils (the cartridge)and that signal is passed onto a phono stage for amplification. That is a simple answer but I am only a vinyl junkie and not an engineer. I know this - It works really well.
If you have not had a chance to sit down and spend some time listening to a good vinyl set-up, do yourself a favor and find someone who has one. Sit yourself down and enjoy. If you want to come out here to Montana and listen to mine you can spend a whole day listening. No charge...

Cool picture.

How is stereo information preserved?

Mono LP's (and cartridges) respond to left/right groove modulations only (2 dimensional groove cutting), stereo uses vertical modulations as well (up/down -- 3d groove cutting).

The way the two are "told apart" by the cartridge has something to do with the position of the magnet(s) or coil(s), I believe there are two positioned at 45 degree angles or something like that.

Yeah, but look at all that nice information in the groove! The picture shows how even a good digitization is a mere approximation of the rich reality!

It really is amazing how something so simple as that can create great sound, it's wild.
