    Yes, it’s ray not the blue-ray. The letter ‘e’ was intentionally avoided to really make it ideal for trademarking. You will find, the Blu-ray is a lot more advanced and better when compared to a DVD. Each one was so excited when DVDs launched in 1997 making it possible playing digital audio/video during our houses. Now, everyone is talking about the newest technology that is even finer quality than DVDs that had become in 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 utilized for reading and writing Blu disc.ray technologies are not an achievement of any single company. Several prominent manufacturers like Apple, Dell, Sony, Sun Microsystems etc formed ray Disc Association which developed fraxel treatments.

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

    (a) More storage capacity A single-sided standard 12 cm DVD can store 4.7 GB of data whereas the same size single layer ray disc can store 25 GB of internet data that’s almost five times greater than a DVD. A dual layer ray disc can store 50 GB of knowledge. Just like DVDs we can easily get mini size ray discs also using the sized 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 rate of 36 Mbps and,

    (c) Video and audio are enjoyed more clarity in comparison with DVD.

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

    (a) Contrary to DVDs which depend upon red lasers operating at 650 nm with and writing data, Blu-ray discs depend upon blue laser that operates at 405 nm. Because the ray technology is with all the short wavelength laser in comparison to DVD, it might embed more data in to the disc which has precisely the same size of 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 hd movies, games.

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

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