CD-R
Compact disc on which data can be recorded (compare with CD-ROM).
The blank disc has a very fine groove that forms a large spiral, starting from the centre of the disc and finishing on the edge. Visible to the laser at the bottom of this groove is a layer of organic dye. During the recording process the laser switches to a higher power and 'burns' a mark in the dye. These marks in the dye are like the pits found on CD-ROM discs, and can be read by the laser operating at a lower power.
