Brian Weaver just sent me a link to the Reckon website, where they have just posted a series of photographs from Chris Supranowitz, a researcher at the Optics Institute at the University of Rochester. Chris has used an an electron microscope to take images of a great many things such as insects, hair and of course LP grooves. It's amazing to see how the grooves undulate, but it's also unnerving to see the big chunks of dust of the vinyl surface!
You can see more of these photos at http://reckon.posterous.com/vinyl-record-grooves-under-electron-microscop.
its amazing device for observations, thanks for sharing.......
