Blu-ray Disc Technology
Due Credit:
Blu-ray Disc, is a next generation optical disc format that was developed by the Blu-ray Disc Association. The format was developed to enable recording, rewriting and playback of high-definition video and for storing large amount of information. Compared to the traditional DVD-R Media, this format can hold up to 25GB on a single layer disc and can hold up to 50GB on a double layer disc. Despite using a blue-violet laser to read and write data, which is different from the laser type used by DVD or CD-R media, Blu-ray devices can be made backward compatible with these media through the use of compatible optical pickup unit.
The future prospects of Blu-ray disc format is even brighter, with several other formats lined up to be released. The BD-ROM format is a read-only version for distribution of HD movies, games and software, etc. The Blue-ray media, BD-R is a recordable format for HD video recording. The BD-RE is a rewritable format for PC data handling and HD video. One more interesting thing about Blu-Ray discs is that you won't need a cartridge to support Blu-ray discs. Unless you need to download some value-added features, you won't need an internet connection either.
