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????

probably got some ideas outta this

Fucking mad lads

“My stripper name was Tanqueray.  Back in the seventies I was the only black girl making white girl money.  I danced in so many mob clubs that I learned Italian.  Black girls weren’t even allowed in some of these places.  Nothing but guidos with their pinky rings and the one long fingernail they used for cocaine.  I even did a full twenty minutes in the place they filmed Saturday Night Fever.  But I made my real money on the road.  Three grand on some trips.  Every time Fort Dix had their pay day, they’d bring me in as a feature and call me ‘Ms. Black Universe’ or some shit like that.  I had this magic trick where I’d put baby bottle tops on my nipples and squirt real milk, then I’d pull a cherry out of my G-string and feed it to the guy in the front row.  But I never used dildos on stage or any shit like that.  Never fucked the booking agents.  Never fucked the clients.  In fact, one night after a show, I caught another dancer sneaking off to the Tate Hotel with our biggest tipper.  Not allowed.  So the next night we put a little itching powder in her G-string.  Boy did she put on a show that night.  Didn’t see her again until ‘The Longest Yard’ with Burt Reynolds.  So I guess she finally fucked the right one.”
