What is Blu-ray Disc?
Blu-ray Disc also known as Blu-ray, BD for short, is the name of a new optical disc format jointly developed by the Blu-ray Disc Association (BDA), a group of the world’s leading consumer electronics, personal computer and media manufacturers (including Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson).

The major application of Blu-ray Disc is as a medium for video material such as feature films and developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data. The Blu-ray offers more than five times the storage capacity of traditional DVDs and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc. Besides the hardware specifications, Blu-ray Disc is associated with a set of multimedia formats. Generally these formats allow for the video and audio to be stored with greater definition than on DVD. This extra capacity combined with the use of advanced video and audio codecs will offer consumers an unprecedented HD experience.
