What is a blue ray disc?

Question

Lately on commercials for new DVDs, they say "now available on DVD and Blue Ray Disc," What is a Blue Ray Disc?

Answer 1

Blu-ray Disc is a next-generation optical disc format meant for high definition video (HD) and high density data storage, and is one of two competing standards for HD optical media. The name Blu-ray Disc is derived from the blue-violet laser it uses to read and write to the disc. A Blu-ray Disc can store substantially more data than a DVD, because of the shorter wavelength (405 nm) of the blue-violet laser (DVDs use a 650-nm-wavelength red laser and CDs use an infrared 780 nm laser), which allows more information to be stored digitally in the same amount of space. In comparison to HD DVD, which also uses a blue laser, Blu-ray Disc has more information capacity per layer (currently 25GB, but test media is up to 200GB). Sony has released 50GB recordable BDs and will soon be releasing 50GB BD media discs.[1] In August 2006, TDK developed a Blu-ray Disc with a 200GB capacity.[2]

A new format produced, in my opinion, to discourage all the dvd burning that goes on. I highly doubt that it is "far superior" to old dvd's. The Playstation 3 will have it when it comes out and it's bumping the price up to, like, $500 - $600. Bunch of crap.
