I recently bought an Alpine in-dash CD player/radio for my car. I've
noticed that whenever I play a CD in it for a few minutes, that after
ejecting it, the CD is quite hot to the touch. Is this normal? If
not (I suspect not -- I just spent two weeks in a rental car on a
trip, and the CD's were always cool to the touch after ejecting -- no
matter how long I played them), can this damage the CD's. Could the
player be defective?

Unlikely. It still plays ok ?

Many in car dash units get quite hot in operation. The fact that a CD
feels warm after ejecting simply reflects the ambient temperature inside
the unit.

A 'head unit' without internal amplifiers would likely stay cooler.
