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.
