Ben Krasnow from Applied Science on YouTube uses his Electron Microscope to compare spinning media. The part of the video that caught my attention is the Vinyl Record. Not only does he show the groove and needle, but he puts it in motion! It’s a great look at how this technology works.

Additionally, I loved how he went into detail about how to prep the record for use in the electron microscope. (Spoiler: he had to make the record and needle conductive.) After the vinyl, he also compares a CD and DVD. The twist is that he also shows how a Capacitance Electronic Disc (CED) compares to the vinyl. You never heard of a CED?

Neither had I until Techmoan covered the RCA CED Videodisc on his YouTube channel. It appears over 1,700 movies were released in the United States alone. Check out the both videos for details on CED.

If you enjoy Electron Microscope pictures like I do, then you’ll enjoy this video.
