Wow, technology is really amazing: "Now, in modern drives, the heads fly at less than 10 nm, a feat that demands not only precise modelling of the air film and head dynamics but also the production of disk surfaces of extraordinary flatness, protected by a 15 nm coating of hard carbon and a lubricant layer only one nm (about 10 atoms) thick."
