While current optical disc technologies such as DVD, DVD+/-R, DVD+/-RW, and DVD-RAM rely on a red laser to read and write data, the new format uses a blue-violet laser instead, hence the name Blu-ray.
The format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data.
