The thrust for an advanced format of data storage on optical disc led to revolutionary introduction of BLU-RAY DISC. This advances in the race against its competitors DVD (Digital Video Disc) & AOD (Advanced Optical Disc) in that it has high storage capacity, advanced security and privacy features and the A/V high quality O/P (generally video) of the media files stored on it make’s it quite unique & gives an edge over the others, letting BD to be widely adaptable in every application possible.
This paper essentially is confined with the structure, construction, reading issues & advantages of the Blu-Ray Disc. To be effective, at every stage the disc is compared with DVD.
The founding stones for the Blu Ray Disc technology were laid in 2002 by the Blu Ray Disc Association (BDA) in an attempt to overcome the drawbacks in DVD's. This attempt has almost reached the zenith & the world now is shortly about to use a disc of an incredible storage capacity & with almost all the apex features incorporated, that ensures user security and privacy and enables one to operate the disc in the most efficient and convenient way ever imagined.
Early in 1997, a new technology emerged that brought digital sound and video into homes all over the world almost thrashing out the then conventional CD's. It was called DVD, and it revolutionized the movie industry. This format ruled the market for over a span of 5 years, but now is facing some very tight challenges. Here are some reasons why there’s been a rush to change from the current format of DVD:
A single-sided, standard DVD can hold 4.7 GB (gigabytes) of information. That's about the size of an average two-hour, standard-definition movie with a few extra features. But a high-definition movie, which has a much clearer image, takes up about five times more bandwidth and therefore requires a disc with about five times more storage. As TV sets and movie studios make the move to high definition, consumers are going to need playback systems with a lot more storage capacity, which a DVD cannot support. Also, more space on a single disc invariably results in higher disc size. This bulky size of the disc is neither convincing nor convenient.
