I don’t care that I supposedly understand how vinyl records work because I still totally think they’re the work of at least some low level sorcery. Trapping sound and music and voices? Come on! Anyways, my disbelief aside of analog technology aside, here’s a cool microscope view of vinyl records being played.
The video by Applied Science also delves into how they managed to capture the footage using an electron microscope. A little bit technical but really interesting stuff.
