Every one was so fired up when DVDs came up into existence within 1997 which produced it possible enjoying digital audio/video perhaps in our homes. Now, people are speaking about the brand-new technology which can be perhaps superior to DVDs that came straight into existence in 2006.

After VCR's and DVDs, advances throughout technology brought us Blu-ray technology. The name blu-ray comes from the fact of which a blue (actually blue-violet) laser is used for reading and writing Blu disc. beam technology is not really an achievement involving any single firm.

Blu-ray discs are better than DVDs throughout the following elements:

(a) More safe-keeping capacity A single-sided standard 12 cm DVD can shop 4. 7 GB of data whereas the identical size individual layer ray disk can store 25 GB of information which is nearly five times greater than a DVD. A double part ray disc can easily store 50 GIG of data. Identical to DVDs we can get little size ray disks also with the dimensions of 8 cm. This mini dvd with single coating capacity can shop 7. 8 GB and dual layer capacity can retail outlet 15. 6 GB.
(b) Higher data rate of thirty-six Mbps and,
(c) Audio and movie are enjoyed even more clarity compared to DVD AND BLU-RAY.

The following are the factors which are responsible in order to embed more information into a beam disc:

(a) Unlike DVDs which depend upon red lasers functioning at 650 nm for reading and even writing data, Digital versatile discs depend on orange laser that runs at 405 nm. As the beam technology is applying the short wavelength laser compared to DVD, it could introduce more data into the disc which includes the same dimensions of a DIGITAL VIDEO DISC.
(b) The thickness of cover part was decreased.
(c) Numerical aperture was increased to 0. 85.

Different formats of ray disk:

(a) BD-R: Recordable format for HD video recording and LAPTOP OR COMPUTER data storage.
(b) BD-ROM: Read only format for pre-recorded contents like hd movies, games.
