Who cares which one sounds better. Dynamic range this, bandwidth that, blah blah.
What I need to know is: which one looks cooler under an electron microscope?

(once again, I vote vinyl)

Huh. I had never heard of the Capacitance Electronic Disc format. Pretty interesting concept.

nice images!

I hadn't heard of that either, actually, but to be honest, I am not up on a lot of consumer video formats. I figured it was just one of those early digital formats that had a limited time frame, and just zoomed over my head/passed me by. Was it not popular? .... anyone ever have a player for those?

A bit before my time...

I was just reading about LaserDisc, and according to wikipedia at least, they could have analog tracks for the audio. This kinda bummed me out actually, as I was wondering about optical analog as a "futuristic" thing, but I guess it's already been tried.

It wasn't analogue in the vinyl sense. It was similar to FM radio. There were two separate FM signals for the stereo channels.
