In the rotating drive world there is constant linear velocity (CLV) and
constant angular velocity (CAV) drives.
On CLV drives the speed of rotation would vary based on the track
(slower in the inner tracks and faster on the outer tracks).? This meant
that the data rate and number of bits/track remained constant.
On CAV drives the rotational speed of the drive doesn't change, this
means that the data rate and number of bits/track changes depending on
the track.

One of our favourite small PC builders, Panrix, questioned this. They
reckoned that having the swap file on the outer, longer tracks of the
drive made it slower, due to slower access times and slower transfer
speeds. They were adamant.
HUH?? Yes, the outer tracks ARE longer, but the whole platter spins at
the same angular velocity, so there can't be any speed difference!?
Did they think there is a whole bunch of magnetic tape inside the
drive?? Wow!
