Blu-ray Disc (also known as Blu-ray or BD) is an optical disc storage medium. Its main uses are high-definition video and data storage. The disc has the same physical dimensions as standard DVDs and CDs.
The name Blu-ray Disc is derived from the blue laser (violet-colored) used to read and write this type of disc. Because of the beam's shorter wavelength (405 nanometres), substantially more data can be stored on a Blu-ray Disc than on the DVD format, which uses a red (650 nm) laser. A two-layer Blu-ray Disc can store 50 gigabytes, almost six times the capacity of a two-layer DVD, or ten and a half times that of a single-layer DVD.
During the format war over high-definition optical discs, Blu-ray Disc competed with the HD DVD format. On February 19, 2008, Toshiba—the main company supporting HD DVD—announced that it would no longer develop, manufacture, or market HD DVD players and recorders, leading almost all other HD DVD companies to follow suit, effectively ending the format war.
Blu-ray Disc was developed by the Blu-ray Disc Association, a group representing makers of consumer electronics, computer hardware, and motion pictures. As of December 9, 2008, more than 1200 Blu-ray Disc titles have been released in the United States and more than 640 Blu-ray Disc titles have been released in Japan. There are expected to be over 1300 Blu-ray Disc titles released in the United States by the end of 2008.

I'll assume that you know what it is, and you are referring to the name?
blu ray comes from the fact that it moves away from the standard 'red' laser used in DVD and HD-dvd players and moves to a smaller wavelength blue-violet laser. They dropped the violet, and changed blue to blu so they can trademark the name, and make it more simple to find using a search engine.
