Blu-ray Disc, which is also known as Blu-ray is the name of a next-generation optical high-definition video disc format developed jointly by the Blu-ray Disc Association, the world’s leading consumer electronics group, media manufacturers, and personal computer companys (including JVC, HP, LG, Apple, Dell, JVC, Hitachi, Mitsubishi, Sony, Panasonic, Pioneer, Philips, Samsung,TDK, Sharp, and Thomson).

There are two competing high-definition DVD formats: HD DVD and Blu-ray Disc. In this article, high-definition DVD refers to both HD DVD and Blu-ray Disc. For a detailed comparison of HD DVD and Blu-ray Disc formats, refer to the DVD/High capacity disc format comparison table.


The Blu-ray format was developed to enable playback, recording, and rewriting of high-definition video. Also for storing large amounts of data. 25GBs can be held on a single-layer disc and can be used for recording over 2 hours of HDTV or in the case of standard-definition TV more than 13 hours. 50gbs can be held on dual-layer versions of the discs.

The term “Blu-ray” was named from the fact that this new format uses a blue-violet laser while most optical disc formats such as DVD, DVD±R, DVD-RAM and DVD±RW, use a red laser to write and read data. Blu-ray products can be made backwards compatible with the use of a BD/DVD/CD compatible optical pickup to allow playback of DVDs and CDs.The blue-violet laser used in Blu-ray uses a 405nm wavelength vs 650nm for the red laser.This allows data to be packed more tightly so it’s possible to fit more data on the same sized disk. The better focus of the Blu-ray laser is what enables Blu-ray Discs to hold 25GB/50GB.
