Have you ever wondered how a vinyl record worked, or what one looked like under an electron microscope? In this video, you'll get to see exactly how one works with very detailed close-up imagery.
Moreover, you'll also get to see what other legacy media storage devices look like under the electron microscope, such as RCA video discs, CDs, and DVDs.
Because electron microscopes use electrons as their medium of creating the images you see, it's important to make a conductive material, which is hard to do with a vinyl record. Because of this, the vinyl had to be coated with a silver coating that would make it conductive of electrons, as you'll see in the video.
As for CDs and DVDs on the other hand, they use aluminum for storage and are already conductive, so the only challenge was getting the thin information-storing layer out of the protective plastic layer.
