Drive makers these days use variable bit rates to increase density of the

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!
