Ahoj,

Jeste na doplneni a pro zajimavost citat (uz postarsi):

The incredible feat of a read/write head:  Today's new generation of disc
drives achieve the engineering equivalent of a Boeing 747 flying at MACH 4
just two meters above the ground, counting each blade of grass as it flies
over. The read/write head floats at 12 millionths of an inch above the
surface of the disc which is turning at 3,600 revolutions per minute. 
Read/write heads position precisely over information tracks which are 800
millionths of an inch apart and the data is electronically recorded at
20,000 bits per inch.
