    Yes, it is ray not the blue-ray. The letter ‘e’ was intentionally avoided making it well suited for trademarking. Company, the Blu-ray is more advanced and better when compared to a DVD. Everyone am excited when DVDs had become in 1997 making it possible playing digital audio/video during our houses. Now, people are referring to the new technology that is even superior to DVDs that had become in the year 2006.

    After VCR’s and DVDs, advances in technology brought us Blu-ray technology. The name blu-ray hails from the fact that a blue (actually blue-violet) laser is used for reading and writing Blu disc.ray technology is not an achievement associated with a single company. A gaggle of prominent companies like Apple, Dell, Sony, Sun Microsystems etc formed ray Disc Association which developed fractional laser treatments.

    Blu-ray discs can beat DVDs in the following factors:

    (a) More storage capacity A single-sided standard 12 cm DVD can store 4.7 GB of data whereas precisely the same size single layer ray disc can store 25 GB of data that is almost half a dozen times greater DVD. A double layer ray disc can store 50 GB of knowledge. Comparable to DVDs we are able to get mini size ray discs also with the size 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) Audio and video are tinkered with more clarity in comparison with DVD.

    The following are the standards that happen to be responsible to embed more data right into a ray disc:

    (a) Unlike DVDs which depend on red lasers operating at 650 nm to read and writing data, Blu-ray discs be determined by blue laser that operates at 405 nm. Because the ray technology is using the short wavelength laser in comparison with DVD, it may embed more data to the disc which includes the identical sized a DVD.

    (b) The thickness of cover 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 videos and PC data storage.

    The exclusive options that come with Blu-ray players are:

    *You can make the playlists.

    *You can make changes for the recorded video and shuffle their order.

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

    *You can record a course while playing a different one.

    *The player automatically looks for the empty space to record new programs around the disc to prevent overlapping of programs.

    *You can randomly visit any point around the disc.
