    Yes, it really is ray not the blue-ray. The letter ‘e’ was intentionally avoided to restore ideal for trademarking. E-mail, the Blu-ray is more advanced and than the usual DVD. Everyone was so excited when DVDs had become in 1997 making it possible playing digital audio/video even in our houses. Now, everyone is talking about the brand new technology that is even finer quality than DVDs that has been around since in the year 2006.

    After VCR’s and DVDs, advances in technology brought us Blu-ray technology. The name blu-ray comes from the fact that a blue (actually blue-violet) laser is employed to read and writing Blu disc.ray technologies are not an achievement of any single company. A small grouping of prominent manufacturers like Apple, Dell, Sony, Sun Microsystems etc formed ray Disc Association which developed fractional laser treatments.

    Blu-ray discs are superior to DVDs from the following factors:

    (a) More storage capacity A single-sided standard 12 cm DVD can store 4.7 GB of data whereas exactly the same size single layer ray disc can store 25 GB of information that is almost half a dozen times greater DVD. A double layer ray disc can store 50 GB of internet data. Much like DVDs we could get mini size ray discs also using the height and width of 8 cm. This mini disc with single layer capacity can store 7.8 GB and dual layer capacity can store 15.6 GB.

    (b) Higher data transfer rate of 36 Mbps and,

    (c) Video and audio are used more clarity in comparison to DVD.

    Are mainly the factors that happen to be responsible to embed more data right into a ray disc:

    (a) Unlike DVDs which be determined by red lasers operating at 650 nm for reading and writing data, Blu-ray discs depend upon blue laser that operates at 405 nm. As the ray technologies are using the short wavelength laser in comparison to DVD, it may embed more data in to the disc that has precisely the same sized a DVD.

    (b) The thickness of canopy layer was decreased.

    (c) Numerical aperture was increased to 0.85.

    Different formats of ray disc:

    (a) BD-R: Recordable format for HD video recording and PC data storage.

    (b) BD-ROM: Read only format for pre-recorded contents like high-definition movies, games.

    (c) BD-RW: Rewritable format for PC data storage.

    (d) BD-RE: Rewritable format for HD video recording and PC data storage.

    The exclusive top features of Blu-ray players are:

    *You can cause the playlists.

    *You could make changes to the recorded video and shuffle their order.

    *You can record high-definition television (HDTV) with improved sound and picture qualities.

    *You can record an application while playing a different one.

    *The player automatically mission to find the empty space to record new programs for the disc in order to avoid overlapping of programs.

    *You can randomly check out any point for the disc.
