What is Blue-Ray storage media?

A Blu-Ray is a spinning disc optical media used for the storage of lage amounts of data in a portable, typically read only format.

CD's, DVD's, Laser disc's, VCD's and HD-DVD's all use(d) a red laser to read information stored on a spinning disc.

Blu-Ray discs use a blue laser to read information stored on the discs. The frequency of a blue laser is much higher, allowing for the stored bits of data to be physically smaller, allowing form more information to be stored on a single disc. A single layer Blu-Ray disc stores about 25 GigaBytes of information. A double layer stores about twice that.

You need a Blu-Ray reader orplayer in order to read or play a Blu-Ray disc. The technology is patented by the Sony Corporation, and is present in the Playstation 3 console.
