varies....CD info is read at tangential velocity...so as the disc moves from inside to outside it slows down...

can't remember the actual velocity of the head-to-disc, but the disc spins up at around 400rpm...although it can get faster (or slower) depending on the density of information on the surface...

what in tintern abbey are you talking about?
josh,

inside every CD deck is a little man who has a little horse. when you put the CD in the deck (via a piece of technological doohickery known in the trade as an 'ole), the little man is normally asleep so it's his wife that wakes him up. He then gets onto his little horse, which accounts for the delay of a few seconds when you insert a CD.

Depending on the horse, and the underhoof conditions, the average little man can go around the inside of a CD player at anything between six and sixty times per minute.

CDs spin faster in older, larger CD players than they do in portable discmans, because there's more headroom.

Hope that clarifies.

Not really. Were older CD's taller then?
