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.

iirc the dreamcast gd rom used a spiral in the opposite direction to be harder to copy

the thing that seems very cool about cds is they seem a bit “hackable”, like people learned to abuse them a bit, for example tracks before track 1, you could only access by rewinding and some players couldn’t do it
