An audio CD rotates at about 500 rpm when reading the inside track and about 200 rpm when reading the outside track. Disks area read inside to out, and 20 min is about 1/4 of the capacity of the disk. The inner radius of the recorded area is 25 mm and the outer 58 mm. You can work it out from these.
