    Yes, it is ray not the blue-ray. The letter ‘e’ was intentionally avoided to really make it suited to trademarking. Company, the Blu-ray is a bit more advanced and much better than the usual DVD. Everybody was so excited when DVDs had become in 1997 making it possible playing digital audio/video even just in our houses. Now, folks are speaking about the brand new technology which is even superior to DVDs that had become in 2006.

    After VCR’s and DVDs, advances in technology brought us Blu-ray technology. The name blu-ray is derived from the fact that a blue (actually blue-violet) laser can be used to read by and writing Blu disc.ray technology is no achievement of the single company. A gaggle of prominent the likes of Apple, Dell, Sony, Sun Microsystems etc formed ray Disc Association which developed fraxel treatments.

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

    (a) More storage capacity A single-sided standard 12 cm DVD can store 4.7 GB of internet data whereas exactly the same size single layer ray disc can store 25 GB of information that’s almost more higher than a DVD. A double layer ray disc can store 50 GB of internet data. Much like DVDs we can get mini size ray discs also with all the size 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 useage rate of 36 Mbps and,

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

    Are mainly the factors which are responsible to embed more data in a ray disc:

    (a) Unlike DVDs which be determined by red lasers operating at 650 nm with and writing data, Blu-ray discs rely on blue laser that operates at 405 nm. Because the ray technology is while using short wavelength laser in comparison with DVD, it can embed more data in to the disc that has exactly the same size 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 videos 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.
