Images of vinyl record grooves taken with an electron microscope by Chris Supranowitz. Would like to see an entire record’s grooves translated into a 3d model, inverted vertically and printed as a mountain range.
And if you thought digital storage was somehow non-physical, the image below is of data stored on a CD – each dot is a 1, with the gaps 0s. Unlike magnetic media where the information is simply an electronic charge, these pits are visible and tangible.
