How does CD-R work?
How does the CD-R work? A CD-R disc is coated with a photosensitive organic dye that allows a user to record information. Once the CD-R disc is placed in the computer, the recording process begins. The laser inside the drive heats the dye to reveal areas that diffuse the light like a traditional CD pit.

What are the physical characteristics of a CD-R?
Physical characteristics. A blank CD-R is not “empty”; the pregroove has a wobble (the ATIP ), which helps the writing laser to stay on track and to write the data to the disc at a constant rate. Maintaining a constant rate is essential to ensure proper size and spacing of the pits and lands burned into the dye layer.
