PS3 goes Blu

Although the PS3 will still support DVD discs – to allow for video playback and backwards compatibility – Sony have announced that they will be using Blu-Ray media for it’s PS3 games.

For those of you not lucky enough to know what Blu-Ray is, you have come to the right place. Blu-Ray discs are similar to DVD’s, except they can hold around 27GB of data, compared to the 4.7GB capacity of DVD’s. They are, unsurprisingly, read using a blue laser, rather than a red one. This fundamental change, is what gives the discs their large capacities. This is explained on the official Blu-Ray website – http//

“The benefit of using a blue laser is that it has a shorter wavelength (405 nanometer) than a red laser (650 nanometer), which means that it’s possible to focus the laser beam with even greater precision. This allows data to be packed more tightly on the disc and makes it possible to fit more data on the same size disc.”

Blu-Ray technology is expected to hit the shelves in 2005, and it’s primary use will probably be for storing films and television programs, using the high definition standard (HDTV). It is expected that Blu-Ray discs (BD-ROM) will replace DVD’s in the next five years.
