About Blu Ray
- Blu-Ray represents the next generation of video discs, and it is one of the most essential components in a modern high-definition home theater entertainment system. In addition to offering a picture resolution 6x greater than traditional DVDs, Blu-Ray offers superior high definition audio.
- The term “Blu-Ray” was derived from the particular wavelength of light used to write and read data from the disc. Since the Blu-Ray’s blue/indigo laser has a shorter wavelength (445nm-475nm) than the traditional DVD’s red laser (650nm), more information can be read and written to the Blu-Ray Disc than from a traditional DVD. This results in an increased data storage capacity per layer of disc. While a traditional DVD, using a red laser, stores 4.7GB of information per disc layer, a Blu-Ray disc, using a blue/indigo laser, stores 25GB of information per layer. In essence, because a shorter wavelength laser was used to manufacture blu-ray discs, more information can be crammed onto roughly the same surface area as a traditional DVD.
