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 blue laser has a wavelength of 405nm compared with the wavelength of 650nm for DVD which utilizes 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). Verbatim's professional optical media feature tighter specifications than the standards given by the relevant standardization bodies.
