Yep, that's related to why CDs use constant linear velocity (i.e. varying the
RPM depending on where the laser pickup is reading) - to maximise the storage
capability of the medium for a constant data rate.  In the analog world, that
shows as changes in the frequency response of the medium as linear velocity
changes.
