MediaRange MR491 (Blu-ray) BD-RE 25GB Re-writable 2x Speed Disc (EACH IN JEWEL CASE):

The advent of Blu-ray technology has led to the introduction of high capacity storage discs to meet the demand caused by the rapid growth of high definition television (HDTV).
Blu-ray discs get their name from blue laser technology.
The shorter wavelength of the laser is the reason it is blue in colour.
The blue laser has a wavelength of 405nm compared with the wavelength of 650nm for DVD which utilises red laser technology.
The benefit of having a blue laser with a shorter wavelength means it is possible to write smaller data pits and therefore vastly increase the amount of data on the disc.
Blu-ray discs offer 3 to 5 times the storage capacity of a standard recordable DVD disc, enabling the recording, rewriting and playback of high definition video (HD).
