Blue Ray and Sony. Reading up on the blue ray player, the blue ray, and the blue ray disc, this piece of technology offers much in the way of potential. Typical DVDs can hold 4.7GB's of information on them, while blue ray discs can hold up to 25GB (single layer). The player uses an ultraviolet light which operates at a much lower wavelength than the typical red lasers we currently use. This feature allows for enhanced photonic storage of data and thus the increase in overall size. There are even some multi-layer single and double sided BD's in production and use that can support anywhere between 250GB - 300GB on a single side. I've heard one possible use for the Blue Ray over the HD is in PC gaming. Piracy is the bane of any game maker's day. What the Blue ray offers over the HD DVD is simply larger size. A tactic the gaming industry is trying to implement is the use of game bloating. They will try as hard as they can to increase the size of the game program in an effort to make it so you can't pirate it. The only real problem i can see with this is the amount of time they are going to invest in bloating the game's code and the cost it will take to simply waste all of the space on a disc. The only thing about the Blue Ray i don't really like is the fact that Sony is the master of creating and developing new technologies, and yet they simply seem to fade out of existence because Sony fail to market them correctly. While they did not create the Blue Ray, they are backing it with their obviously failing release of the PS3.
