A CD burner is used to write (burn) the data on a CD.

How is the data stored on a CD ROM?

When reading a CD-ROM, a low power laser beam is focused on the rotating CD-ROM and its reflection is viewed by the read head. When the beam reflects back from the CD- ROM, it’s intensity changes as it moves from “land” to “pits”. These variations in the laser beam are decoded as data by the CD-ROM drive.
