Blu-ray is the type of disc used for [[Playstation 3|PlayStation 3]] games and for playing [[high-definition]] (HD) movies. In the past, there were other standards for such movies, such as the [[HD DVD]] format. Blu-ray won what is called the ''[[format war]]'' between 2006 and 2008. A dual-layer Blu-ray disc can store up to 50GB ([[gigabyte]]s) of data. This is over five times the capacity of a [[DVD]], and over 70 times more than a [[Compact disc|CD]] or [[VCD]]. The disc was developed by the [[Blu-ray Disc Association]] (BDA), a group of consumer electronics, [[personal computer]] and media manufacturers, and released in 2006. The format was developed for recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data. Older optical disc technologies such as DVD, DVD±R, DVD±RW, and DVD-RAM used a red [[laser]] to read and write data. The new format used a blu laser instead. This is where the name is from. == Related pages == * [[DVD]] * [[HD DVD]] * [[Compact disc]] (CD) == Other websites == {{commonscat|Blu-ray Disc}} * [http://www.blu-raydisc.com/ Blu-ray Disc Association] {{Webarchive|url=https://web.archive.org/web/20100110062005/http://www.blu-raydisc.com/en/Technical/TechnicalWhitePapers/General.html |date=2010-01-10 }} * [http://www.hughsnews.ca/faqs/authoritative-blu-ray-disc-bd-faq The Authoritative Blu-ray Disc FAQ] by Hugh Bennett * [http://www.cdfreaks.com/reviews/Blu-ray-vs_-HD-DVD/ Blu-ray vs. HD-DVD] {{Webarchive|url=https://web.archive.org/web/20081019054852/http://www.cdfreaks.com/reviews/Blu-ray-vs_-HD-DVD/ |date=2008-10-19 }} [[Category:Optical discs]] [[Category:Video Discs]] {{Tech-stub}}
