A large, clear cylindrical mold is lowered onto a rotating black disc, which is then pressed down by a mechanical arm. The scene shifts to a close-up of a needle etching a spiral groove onto a spinning disc, followed by a disc being submerged in a green liquid bath. A metal rod presses down on a piece of paper with printed text, then a large mechanical press descends onto a disc. Finally, a red-lit disc spins rapidly within a complex machine, with various mechanical arms and components moving around it.
