Blu Ray is the next step in optical media formats from CD and DVD. Initialy developed for the HD (high definition) video that is now availble for recording, rewriting and playback as well as the storage of large amounts of data. A Blue Ray disc offers a capacity 5 times greater than a traditional DVD at 25GB.
Blu Ray is currently supported by over 200 of the worlds consumer electronics, computing, recording, computer game and music companies. All the Hollywood studios back this format as well as countless numbers of smaller studios.
While current optical disc technologies such as DVD rely on a red laser beam to write and read data to the disc, the blu ray format uses a blue-violet laser instead (hence the name Blue Ray) the blue-violet light has a shorter wavelength to that of the red light, which makes it possible to focus the laser more precisely. This allows the data to be stored more tightly together on the disc's surface, whilst being the same size as a traditional CD or DVD. This is what allows the disc to contain the larger capacity of 25GB.
A Blu Ray disc can hold:
Over 9 hours of HD (high-definition video on a 50GB disc.
About 23 hours of SD (standard-definition) video on a 50GB disc
