    Yes, it is ray not the blue-ray. The letter ‘e’ was intentionally avoided making it ideal for trademarking. Company, the Blu-ray is a bit more advanced and much better compared to a DVD. Every one was so excited when DVDs launched in 1997 making it possible playing digital audio/video even in our homes. Now, people are talking about the new technology which can be even better than DVDs that has been around since in 2006.

    After VCR’s and DVDs, advances in technology brought us Blu-ray technology. The name blu-ray hails from the reality that a blue (actually blue-violet) laser is utilized for reading and writing Blu disc.ray technology is not an achievement from a 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 be better than DVDs from the following factors:

    (a) More storage capacity A single-sided standard 12 cm DVD can store 4.7 GB of information whereas exactly the same size single layer ray disc can store 25 GB of information that is almost 5 times greater DVD. A double layer ray disc can store 50 GB of internet data. 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 transfer useage rate of 36 Mbps and,

    (c) Audio and video are tinkered with more clarity compared to DVD.

    The following are the standards which can be responsible to embed more data in to a ray disc:

    (a) Contrary to DVDs which be determined by red lasers operating at 650 nm to read by and writing data, Blu-ray discs depend on blue laser that operates at 405 nm. Because ray technology is using the short wavelength laser in comparison to DVD, it can embed more data into the disc which includes precisely the same size of 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 will make changes on the recorded video and shuffle their order.

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