A Look At A Record Groove Through An Electron Microscope

OK, this is just plain cool. Last week we looked at a guitar string playing in real time, today we'll take a closeup look at the groove of a record with an electron microscope.

As an added bonus, you'll also get a closeup look at a CD and video disc, as well as a terrific explanation of what's happening by Ben Krasnow from his Applied Science blog. This is a lot more complicated than you think.
