From BENQ website:
"Consumers can burn the data side on a disc as normal, then flip the disc over and burn a precise, iridescent label with their desired text and graphics using the same laser that burns the data – no printer, permanent marker or adhesive labeling is required. LightScribe labels require no ink supplies, can be burned anywhere and do not take up data space or peel off in the disc drive. The LightScribe patented technology was developed by HP."
