What is CD-ROM speed?

CD-ROM drives are rated with a speed factor relative to music CDs. If a CD-ROM is read at the same rotational speed as an audio CD, the data transfer rate is 150 Kbyte/s, commonly called “1×” (with constant linear velocity, short “CLV”). At this data rate, the track moves along under the laser spot at about 1.2 m/s.
