Everyone was very excited when DVDs had become in 1997 making it possible playing digital audio/video during our homes. Now, everyone is talking about the brand new technology that is even finer quality than DVDs that has been around since in 2006.

After VCR’s and DVDs, advances in technology brought us Blu-ray technology.

(a) More storage capacity A single-sided standard 12 cm DVD can store 4.7 GB of information whereas the same size single layer ray disc can store 25 GB of internet data which can be almost half a dozen times higher than a DVD. A dual layer ray disc can store 50 GB of data. Just like DVDs we can easily get mini size ray discs also with the size 8 cm.

(a) Despite DVDs which depend on red lasers operating at 650 nm to read and writing data, Blu-ray discs depend on blue laser that operates at 405 nm. Because ray technology is while using short wavelength laser when compared with DVD, it might embed more data in to the disc containing exactly the same sized a DVD.

(b) The thickness of cover layer was decreased.

(c) Numerical aperture was increased to 0.85.
