Blu-ray

An HD-DVD format that uses a 405nm-wavelength blue-violet laser technology, in contrast to the 650nm-wavelength red laser technology used in traditional DVD formats. The rewritable Blu-ray disc, with a data transfer rate of 36Mbps, can hold up to 27GB of data on a single-sided single layer disc (compared to the traditional DVD��s 4.7GB capacity), which amounts to about 12 hours of standard video or more than 2 hours of high-definition video.

The Blu-ray format was developed jointly by Sony, Samsung, Sharp, Thomson, Hitachi, Matsushita, Pioneer and Philips, Mistubishi and LG Electronics.
