You can see that the basic read-write mechanism is exactly the same as in today's drives: there are multiple platters (light blue) made up of individual sectors (dark blue) that can Instead, the heads were allowed to "land" on a special area of the disk surface upon spin-down, "taking off" again when the disk was later powered on. There's just a large shiny, circular "plate" of magnetic material called a platter, divided into billions of tiny areas.
