LightScribe is HP's new, long-delayed, and still-not-shipping technology for labeling recordable CDs and DVDs. Basically, you have to buy special discs coated on the non-data side with a dye, and special drives. Then, after you burn your disc, you flip it over and use special software that uses the drive laser to burn a "silkscreen-quality" monochrome graphical label into the disc.
Unfortunately, what appears to be a botched press release from MKM/Verbatim is contributing to the ongoing stumbling introduction of LightScribe, since it says they'll be selling "stampers and ink" for LightScribe-enabled drives.
I've written about the mess here:
