Blu ray technology.

As said necessity is the mother of invention, the need for huge storage as unveiled a new product which was developed by a group of organizations. A 30 GB single layer disc called Blu-ray. It incorporates an s\w 405 nm blue violet laser to record, rewrite and playback the data. A cartridge protects the disc’s surface from dust and fingerprints. Also using this technology Toshiba has unveiled a next generation storage disc with 110 GB capacity. It is basically twin sided double layer construction for more data packaging. Plans are there to create large storage discs by making use of multiple layers and both sides of the discs. Also Nano-technology could come to the rescue. Either way there is a need to create devices that could effectively use these disks.
