CD's use IR lasers, and hold about 650Mb of data. DVD's use red lasers, and hold about 4.7Gb of data.

The advantage of a blue laser would be that you could make a new disk that would hold maybe 20Gb of data. This will be needed to store HDTV movies.

However, please note that Cree does not yet have a commercial solid state blue laser. Nobody does. I believe Cree is several years behind the Japanese in their blue laser research. We can only hope that when they do figure out how to make one, that SiC turns out to be an advantageous substrate.
