invent by philip in 1973 to springboard michael jackson to stardom the compact disc (or “CD”) is a round disc 100mm in diameter which has shiny pits that represent ones and zeros these ones and zeros encode data and that data encodes music. block rockin beats. this was called black book later they realised you could encode other data onto these discs and they call that yellow book then at some stage they made it so CDs could be made of plastic and you could zap them with a laser and make your own. this was good for stealing music and games all in all CDs are round. then they made DVD. then HD-DVD. then the playstation 3 I think.

fun fact, CDs are literal spirals with one long track, not sectors like a hard drive. they are designed to be able to play with no buffering so the bits can go directly from the laser to the DAC. it’s basically a phonograph but with digital encoding.

thats not exactly true, there’s also to 8-to-14 decoder and the time codes. but still basically no ram required.

my favorite is the 80mm diameter mini-cd (compacter disc?) that stores a lot less data but looks 10x more like you're doing some hollywood super hacker poo poo. had to give up that life when I switched to slot-loading mac laptops

records are much cooler but CDs are significantly cheaper and take up less space.

I.e. the holes get elongated as you approach the outer edge of the disc

To get anything from the US or Europe to the UK can double the price. I paid $45 for shipping two albums recently and will probably have to pay VAT and handling on top when they arrive.

there’s a fair number of “loudness wars” stuff from the 90s through the 2000s where the CD releases were way more dynamically compressed than the vinyl but it’s not stuff I listen to much plus a lot of the current streaming versions are higher quality listen to the original vs. remasters of pretty hate machine if you want very clear example of what that’s about
