- 2x 10pk Spindle Hard Coat protective layer Excellent playback performance 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 & therefore vastly increase the amount of data on the disc. Blu-ray discs offere 3 to 5 times the storage capacity of a standard recordable DVD disc, enabling the recording, rewriting & playback of high definition video (HD).
