The advent of Blue-ray technology led to the introduction of high-capacity storage discs to meet the demand generated by the rapid rise of high-quality television. Blue-ray discs derive their name from the blue laser technology. This blue color is due to the fact that the laser wavelength is shorter. Using a blue laser with a shorter wavelength allows for writing smaller data pits, thus significantly increasing the amount of data on the disc. Blue-ray discs offer a higher storage capacity than a standard recordable DVD; they allow recording, rewriting, and playback of video content.
