High Definition Video Discs (Blu-ray & HD DVD) by Genre

Blu-ray is one of two competing high-density video disc formats, the other being HD DVD. Both formats use a higher-frequency violet laser (DVD and CD use red & near-infrared, respectively) to achieve higher data-storage density -- hence the name Blu-ray. There is still considerable doubt as to which format will ultimately gain wider acceptance, and become the de facto standard.

As I mentioned earlier, Blu-ray seems to have the upper hand at the moment, although many maintain that the HD DVD technology is superior and should become standard. The question may become moot, as the formats are not as irretrievably incompatible as in the bygone VHS / BetaMax format war. There are already players capable of reading either type disc, although they are a bit more expensive than single-format players.

Amazon.com carries about as many Blu-ray, and HD DVD discs as anybody, but they haven't really made them easy to find. (You have to come here for that!)
