Style Name:50 pack The advent of Blu-ray technology has led to the introduction of high capacity storage discs to meet the demand cause 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). For use only in drives or recorders that support Blu-ray Discs without cartridge. Laser Wavelength: 405nm. Hard Coat protective layer. Extremely long archival life. Excellent playback performance. BD-R is for use in BD writers and recorders. The White Inkjet disc has a white surface for inkjet printing with transparent hub and printable diameter 40 - 118mm.
