What are Blu-Ray Discs (BD)?
Blu-ray, also known as Blu-ray Disc (BD) is the name of a next-generation optical disc format jointly developed by thirteen leading consumer electronics and pc companies (Dell, Hitachi, HP, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson). The format was developed to enable recording, rewriting and playback of high-definition television (HDTV). Blu-ray makes it possible to record over 2 hours of HDTV, or more than 13 hours of SDTV on a 25GB disc. There are also plans for higher capacity discs that are expected to hold up to 50GB of data.
