It’s 2018 and I still have no clue how CDs work. It’s a shiny disc, how do they get data on that, let alone that much?? Magic
Like a vinyl disc, where a physical groove is marked into the vinyl, a laser marks the ink of a CD in a similar manner.
A laser (your disc drive) can then look at the pattern in the ink and understand it.There’s no grooves on a CD tho???
They’re just really tiny, hence the laser. The smaller grooves means that more info can fit on a disc of the same size.
Man how the fuck did they figure out how to make that
They took the vinyl concept and made it smaller. Like how they took the concept of computers and made them small enough to fit in your hand
