A17 g audio compact disk has a diameter of 12 cm. the disk spins under a laser that reads encoded data. the first track to be read is 2.3 cm from the axis; as the disk plays, the laser scans tracks farther and farther from the center. the part of the disk directly under the read head moves at a constant 1.2 m/s. when a disk is inserted, it takes 2.4 s to spin up from rest.
