Easy: Drives don't have the same speed on all tracks. The platters are
built-up from zones with different recording densities: zones near the
center of the platters have a lower recording density and hence a lower
datarate (less bits/second pass under the head). Zones at the outer
diameter have a higher recording density and a higher datarate.
