Following a technical discussion held in Tokyo earlier this week, Sony has confirmed that, as suspected, PS3 discs will take advantage of Blu-Ray technology. Blu-Ray discs have a storage capacity five times greater than that of standard DVDs, so games and high-definition movies would normally have 27 GB to play with. And that’s just a single layered disc.
However, Sony has confirmed that PS3 will use its own standard of Blu-Ray discs, which are read-only and have a slightly reduced capacity of 23 GB. But that's no great loss. This system can also maintain full support for standard DVDs. That means that ‘old fashioned’ DVD movies should run fine, and the option for PS2 backwards-compatibility can be kept open.
The first Blu-Ray video players are intended for release before March 2005, and once this technology has been launched Sony will proceed to confirm further PS3 technical specifications. Expect more PS3 news before then!
