The Blu-ray Disc belongs to a new generation of optical discs capable of organizing the data at high density. Blu-Ray technology is based blue-violet laser. The laser Blue operates at a wavelength of 405 nm, while older technology such as DVDs and CDs are based on red and infrared laser operating at 650 and 780 nm. Since the length of wavelength is shorter with a blue laser, Blu-ray the new technology makes it possible to store much more information

The advantage of Blu-ray is that the laser beam can be focused more on the disc surface. Concentration without failure, a low point occurs at the disk surface, and when the points are smaller there, Naturally, there will be space for more information on each disk. The minimum spot size of any laser depends on a diffraction phenomenon which arise naturally called. The small ray of light sent by a laser always differ in a broad beam of time due to the nature of diffraction waves. Diffraction also occur waves against an obstruction. By reducing the wavelength of a laser, which can affect the diffraction.

Blu-ray diffractions is also affected by the fact of the lens used to focus the light has a numerical aperture of the lens is in regular DVD - 0.85 instead of 0.6. Blu-ray-based devices also equipped with a dual lens system of supreme quality, and the cover layer becomes thinner, to prevent the optical effects. This allows Blu-ray laser to focus on much smaller spots. The optical improvements are accompanied by a new method of encoding data it can store more data on the Blu-ray.

The standard for Blu-ray technology has been developed as a joint venture between several large PC manufacturers and consumer electronics such as Sony and Philips. The group is called Blu-ray Disc Association (BDA). The first Blu Ray has been released in Japan in 2003 by Sony. Today, Samsung, JVC, Matsushita (Panasonic) and LG Electronics are all examples of companies using Blu-ray technology in their products. Hewlett Packard has announced it will release desktop PCs equipped with Blu-ray technology in late 2005.

The main competitor to Blu-ray HD DVD is also capable of storing more information a normal DVD. The Blu-ray is, however, for more information by layer HD DVD - 25 GB vs 15 GB. The Blu-ray, however, probably more expensive to support, at least initially, which can make the HD DVD of an alternative tempting. In a Blu-ray, the data is stored near the surface. This made the first Blu-ray is extremely vulnerable to scratches and many users preferred the most difficult of HD DVD. Since 2004, all Blu-ray discs are coated with a transparent polymer called Durabis "which makes them much more durable. According to the developers DURABIS Texas Instruments Company, a Blu-ray coating works even after being attacked with a screwdriver.
