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
well they looked at a record and said “How do we fit more information on this?” to which the reply is “Well either you make the record bigger or the grooves smaller” and making the grooves smaller is way more convenient so they say “Well how do we make the grooves smaller?” and that’s when a total madman comes out with eyes flashing and yells “WITH A LASER!”
And that’s how the CD was invented
how did they figure out how to fit information in grooves in a piece of vinyl in the first place????
You can cut as much plastic out of your life as you want, you can eat as much vegan food as you like and you will never be nearly as “eco-friendly” as Bob Who Did Not Take Three Holiday Flights This Year.
Up now on my eBay! Classic indie comic from 1997! Optic Nerve #4 by Adrian Tomine! Also up for grabs: my superheroine comic collection (70’s-80’s stuff), random Radio Comix books and various indie comics! My house is super small, and I am still selling off thirty years’ worth of collectibles to raise money for ongoing back taxes & various upcoming large expenses, so every little bit helps. Thanks for looking & sharing!
