Ben Krasnow of Applied Science describes how he made a stop motion animation of a phonograph needle in an LP groove using an electron microscope.
The animation of the needle in the groove is fascinating, but what he had to do to make it work is even more interesting.
Krasnow also shows electron micrographs of other recording media, such as DVDs.
