Blu-ray Disc (also known as Blu-ray or BD) is an optical disc storage medium designed to supersede the standard DVD format. Its main uses are for storing high-definition video, PlayStation 3 games, and other data, with up to 25 GB per single layered, and 50 GB per dual layered disc. The disc has the same physical dimensions as standard DVDs and CDs.
Blu-Ray technology is so-named because of its use of blue laser technology in storing and reading data. Being on the shorter wavelength end of the light spectrum than the red laser used for DVD and CD technologies (405 nanometer for Blu-Ray versus 650 nanometer and 780 nanometer for DVD and CD technology), blue laser is capable of storing a much larger amount of data using the same space because of a much smaller “spot size” requirement. Blu-Ray’s 405nm wavelength blue-violet laser uses an 0.85nm pickup aperture.

Why should You upgrade from DVD to Blu-ray?
The simple answer is HDTV. If you’ve ever seen high-definition (HD) video on an HDTV, then you know just how incredibly sharp the picture is and how vivid the colors are. In fact, HD offers five times the amount of detail compared to standard-definition (SD). The problem with today’s DVDs is that they only support SD and don’t have the necessary storage capacity to satisfy the needs of HD. That’s where Blu-ray comes in, it offers up to 50GB of storage capacity and enables playback, recording and rewriting of HD in all of the HD resolutions including 1080p. The format also supports high-definition audio formats and lossless audio.
In addition to the greater video and audio quality, the extra storage capacity also means there will be plenty of room for additional content and special features. This combined with the new BD-J interactivity layer adopted by Blu-ray will bring the menus, graphics and special features to a whole new level. For example, you will be able to bring up the menu system as an overlay without stopping the movie, and you could have the director of the movie on the screen explaining the shooting of a scene while the scene is playing in the background. The advanced interactivity combined with the networking features of Blu-ray will also allow content producers to support new innovative features such as downloading extras, updating content via the web, and watching live broadcasts of special events.
Thanks to the greatly enhanced HD video and audio quality as well as the advanced interactivity and networking features, Blu-ray represents a huge leap forward in the DVD viewing experience and will offer consumers an unprecedented HD experience.
