CD's operate at a constant linear velocity, so they will spin faster at the beginning (inside) tracks.

The reason for the variation from disc to disc is how well the center hole is centered. If it isn't perfectly centered, everything will vibrate as the disc spins. By the third track it has slowed enough that the vibration doesn't cause a problem.
