The dimensions of the head are impressive. With a width of less than a hundred nanometers and a thickness of about ten, it flies above the platter at a speed of up to 15,000 RPM, at a height that’s the equivalent of 40 atoms. If you start multiplying these infinitesimally small numbers, you begin to get an idea of their significance. Consider this little comparison: if the read/write head were a Boeing 747, and the hard-disk platter were the surface of the Earth:From here. Amazing. Just. Freaking. Amazing.
*The head would fly at Mach 800 [Mach 1 is the speed of sound- 800 times that]
*At less than one centimeter from the ground
*And count every blade of grass
*Making fewer than 10 unrecoverable counting errors in an area equivalent to all of Ireland.

That's blowing my mind. Thank God I'm at work and sober or I'd be face-planted at my desk at home pondering this.
