An incredible example of what can be done with laser-cutting, Amanda Ghassaei’s project “Laser Cut Record” features music inscribed directly into cut discs of maple wood, acrylic, and paper, resulting in lo-fi but playable records. via bldgblog.
Super-duper closeup of a vinyl record’s indentations:
This is a close up image of a vinyl record, taken with an electron microscope. The dark objects in the grooves are tiny particles of dust. The laser cutter cannot make such precise cuts because the width of the beam is too large, so the grooves on my records are about 1-2 orders of magnitude larger in every dimension than these grooves.
