Blue Ray is a general term for the next-gen optical disc technology for storing high-definition video. It is based on the 405nm wavelength "blue ray" laser to provide higher storage density on the disc.

Currently there are two opposing parties competing for the industry standard, they are:

• Blu-ray Disc (Sony, Disney, Apple, and more / BDA) and


• HD DVD (Toshiba, Intel, Microsoft, and more / DVD Forum).

It should be noted that several companies do support both format, including: Paramount, Warner Bros., Hewlett Packard, and etc.
