Not if you stretch the bits, as older drives did. You are still covering 
more linear distance per unit time but the magnetic data is smeared out 
just enough to counteract this. This is the disk equivalent of the 
Lorentz contraction. :-)


So the relative speed of your head over the platter is faster but the 
observable effect (data transfer rate) is the same as it is on the inner 
tracks.
