New, potential replacement for the optical DVD, that is compatible with DVD standard. Recorders are currently being released that can place 6 hours of digital terrestrial HDTV and 9 hours for standard digital satellite television.
Burners and storage discs are both comparatively expensive. The main backers of this standard are Sony (Playstation 3), Matsushita (Panasonic), Dell, HP, Hitachi, LG, Philips, Pioneer, Samsung, Sharp and TDK.
How much data can you fit on a Blu-ray disc?
A single-layer disc can hold 25GB. A dual-layer disc can hold 50GB.
To ensure that the Blu-ray Disc format is easily extendable (future-proof) it also includes support for multi-layer discs, which should allow the storage capacity to be increased to 100GB-200GB (25GB per layer) in the future simply by adding more layers to the discs.
