Blu-Ray Disc Format

Blu-Ray Disc Format - a format developed by the 'Blu-Ray Disc Founders,' namely Hitachi, LG Electronics, Matsushita, Pioneer, Philips, Samsung, Sharp, Sony, and Thomson. This uses a new blue-violet laser technology that has a smaller laser beam width than a conventional laser beam and so can store more data on a standard 12cm optical disc. A single-layered Blu-Ray Disc can store up to 27GB, and a dual-layered double-sided Blu-Ray Disc can store up to 54GB.
