Covering more distance in the same time means increased speed to me!

Clearly, on a disk, the outer tracks ARE moving faster, in terms of linear velocity.
If the data is written at a constant data transfer rate, and the motion of the disk is the same when reading as for writing, then the data transfer rate in unaffected.
With CAV, the physical width of the bits is larger on the outer tracks, where the linear velocity is higher.
