The following information was cut and pasted after performing Googel search on Blu-ray and on LightScribe.
Blu-ray is a next-generation optical disc format jointly developed by the Blu-ray Disc Association (BDA) ...... The format offers more than five times the storage capacity of traditional DVDs and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc. This extra capacity combined with the use of advanced video and audio codecs will offer consumers an unprecedented HD experience.
While current optical disc technologies such as DVD, DVD±R, DVD±RW, and DVD-RAM rely on a red laser to read and write data, the new format uses a blue-violet laser instead, hence the name Blu-ray. The benefit of using a blue-violet laser (405nm) is that it has a shorter wavelength than a red laser (650nm), which makes it possible to focus the laser spot with even greater precision. This allows data to be packed more tightly and stored in less space, so it's possible to fit more data on the disc even though it's the same size as a CD/DVD. This together with the change of numerical aperture to 0.85 is what enables Blu-ray Discs to hold 25GB/50GB.
LightScribe is an optical disc recording technology that utilizes specially coated recordable CD and DVD media to produce laser-etched labels. LightScribe was invented by Hewlett-Packard engineer Daryl Anderson, and licensed by HP to numerous hardware manufacturers, media manufacturers and software developers. Although currently limited to desktop and laptop PC DVD/CD drives, HP has ambitions to make LightScribe present in consumer electronics products such as stereo-component CD recording decks and set-top DVD recorders.[1]
The purpose of LightScribe is to allow users to create direct-to-disc labels (as opposed to stick-on labels), using their optical disc writer. Special discs and a compatible disc writer are required. After burning data to the read-side of the disc, the user simply turns the media over and inserts it with the label side down. The drive's laser then etches into the label side in such a way that an image is produced.
