Why do people have to write such ignorant, smart@rse comments?
The original poster was CORRECT inasmuch as the RPM of a CD *does* change from the centre to the edge. However, they meant throughout the DURATION of the playback - from centre (programme start) to edge (programme end), and NOT at any one moment in time! - D'oh!
CDs are recorded in what's known as a CLV format (constant linear velocity) as opposed to CAV (constant angular velocity) - so the rotational speed gradually slows down towards the end of the recording.
It's usually a good idea to check your understanding of the facts before taking the p*ss out of other people.
