We don't know about you, but we generally don't give much thought to our hard drives or how they work. And that's a shame because, as you'll find out in the video after the break, they're veritable miracles of modern science. Bill Hammack, also known as Engineer Guy, takes us on a detailed tour of the inner workings of the ubiquitous hard disk drive -- from the Lorentz Force driven arm, to the head that floats a mere 10nm above the layered cobalt platters thanks to the wonders of aerodynamics. Maybe after this lesson in modern magnetic storage from Mr. Hammack you'll appreciate how much more there is to storing your collection of Mission of Burma b-sides than simply printing ones and zeros on a shiny, spinning thing.
