Several commercial CD-R and CD-RW optical recording disks are exposed to intense white light sources (Halogen Tungsten and High-Intensity Discharge) at different exposure times under three minutes. Main analog playback parameters for CD-R and CD-RW optical recording disks are identified and characterized. The contents of a test disk is recorded onto each CD-R and CD-RW disk using a commercial rewritable/recordable disk drive. For each disk, written marks are imaged under a Nomarsky/Bright field optical microscope before and after exposure. Using a dynamic tester carrier-to-noise ratio and timing jitter are determined before and after exposure. AZO-dye CD-R disks, cyanine-dye CD-R disks, and CD-RW disks show considerable reduction in written mark contrast after exposure. Pthalocyanine-dye CD-R disks do not show significant changes in the mark contrast after exposure. Dynamic tester results confirm the mark contrast results and give insight into playback behavior of exposed disks.
