    blu-ray is sony backed technology supported by the ps3 and hence will survive only if ps3 is a success and competes with MS backed HD DVD format (xbox 360)

    it requires a different writer ... which damn costly as of now

    for tech specs .... wikipedia and google

    Blu-Ray Disc

    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. Its competitor is #-Link-Snipped-#. A BD same size as that of a DVD or CD.

    Blu-ray gets its name from the shorter wavelength (405 nm) blue laser that, in addition to other techniques, allows it to store substantially more data on the same sized disc than DVD, which uses a longer wavelength (650 nm) red laser. Blu-ray was jointly developed by a group of leading consumer electronics and PC companies called the Blu-ray Disc Association (BDA), which succeeded the Blu-ray Disc Founders (BDF).

    One single-layer Blu-ray Disc (BD) can hold about 25 GB or over two hours of HD video plus audio, and the dual-layer disc can hold approximately 50 GB.

    Blu-ray is currently supported by more than 170 of the world's leading consumer electronics, personal computer, recording media, video game and music companies.

    BD Players will be common in 2006-2007. In 2003, Sony released its first Blu-ray recorder in Japan with a price tag of around $3,000.

    Currently BD are being used in Japan and US. LG and SONY launched Blu-ray disc players in India in August 2006. TDK - Wikipedia recently announced that they have created a working experimental Blu-ray Disc capable of holding 200 GB of data on a single side (six 33 GB data layers).
