The name Blu-ray Disc is derived from the blue-violet laser used to read and write this type of disc. Because of its shorter wavelength (405 nm), substantially more data can be stored on a Blu-ray Disc than on the DVD format, which uses a red (650 nm) laser. A single layer Blu-ray Disc can store 25 gigabytes (GB), over five times the size of a single layer DVD at 4.7 GB. A dual layer Blu-ray Disc can store 50 GB, almost 6 times the size of a dual layer DVD at 8.5 GB.
Blu-ray Disc is similar to PDD, another optical disc format developed by Sony (which has been available since 2004) but offering higher data transfer speeds. PDD was not intended for home video use and was aimed at business data archiving and backup.
Blu-ray Disc has won the format war against its rival HD DVD, developed by Toshiba, and is now the dominant next-gen format
The Blu-ray Disc Association (BDA) is the industry consortium that develops and licenses Blu-ray Disc technology and is responsible for establishing format standards and promoting business opportunities for Blu-ray Disc. The BDA is divided into three levels of membership: the Board of Directors, the Contributors, and the General Members. [1]
The "Blu-ray Disc founding group" was started in May 2002 by nine leading electronic companies: Sony, Matsushita, Pioneer, Philips, Thomson, LG Electronics, Hitachi, Sharp, and Samsung. Spearheaded by Sony Corporation, on February 19th 2002 the companies announced [2] that they were the "Founders" of the Blu-ray Disc and later changed their name to the "Blu-ray Disc Association" on May 18, 2004 to allow more companies to join their development. Some examples of companies that signed in include Apple, TDK, Dell, Hewlett Packard, The Walt Disney Company, Warner Bros. and Universal Music Group. As of December 2007, there are more than 250 members and supporters of the Association.
The Vidabox Max was the first Blu-ray Disc and HD DVD player.
