Why are blank DVDs purple?
Blank DVDs are purple because of the heat-sensitive organic dye (like Azo dyes) used in their recordable layer, which appears purple or blue before burning and changes color as a laser "burns" data into it, creating the dark/light patterns that represent 1s and 0s, unlike silver pressed DVDs with no dye.Why are some DVDs purple?
