522592 2007-02-05 05:02:00 RPM is RPM. Whatever RPM the inside of the cd is doing, the outside is doing the same. Don't confuse that with velocity.

While under normal operating conditions, this must be true, in this case it appears that the outer rim did indeed rotate at a higher RPM than the inner part of the cd, hence parting company on a very permanent basis.:thumbs:

Good point, wotz. Change one word of the quote: " ... drive can attain *high* speed at the outer edge ..." and all is well.

andy, it may have been the other way around. After intense and detailed forensic investigation (read: I took a glance at the fragments) it appears that the outer edge was the first part of the disk to sit down on the job. The inner edge, still grimly determined to fill its last alloted minute of revolutions per, twirled on ...

What I meant was that the CD's (still, I think, although there are Constant Angular Velocity drives or modes) spin at different rates depending on where the head is, in order to keep the data rate to the host constant. Mind you, I guess that would mean they spin faster when they're transferring from the inside of the disk, so my mistake.
