Wikipedia, Apr. 27, 2010 (Blu-ray Disc (also known as BD or Blu-ray) is an optical disc storage medium designed to supersede the standard DVD format. Its main uses are for storing high-definition video, PlayStation 3 video games, and other data, with up to 25 GB per single layered, and 50 GB per dual layered disc)
Blu-Ray Disc Association website, Apr. 27, 2010 (What does the name Blu-ray Disc mean? The name Blu-ray Disc refers to the blue laser that is used to read from and record to a Blu-ray Disc. In comparison to a red laser, as used in DVD and CD, a blue laser allows for a much higher density and hence larger storage capacity. "Blu" is intentionally spelled without an "e" to allow for a distinctive registration of the trademark name. What is the correct abbreviation of Blu-ray Disc? Blu-ray Disc can be shortened down to "BD")
