The blue ray disc was a product of the joint effort of the world's leading consumer electronics, computers and media manufacturers. Their common objective was to develop a format that would support the recording, rewriting, and playback of HD (high definition video) and also store an increased amount of data. The result was the blue ray disc that has 5 times the capacity of normal DVDs. A blue ray disc has a capacity of about 25GB compared to that of a normal DVD which is around 4.7GB. This invention made it possible to have the advanced video and audio codec that come with HD video to be comfortably stored in one location.
The invention of the blue LED was key to the creation of this technology. Blue rays are shorter than the red laser waves that are used for reading the content in DVDs. Their shorter wave length i.e. 450nm compared to the red laser length of 650nm means that data can be stored in the more yet smaller pits available with the blue ray disc compared to that in the DVDs. This is why a single layer Blue ray disc has a capacity of around 25GB compared to a single layer DVD which can only hold 4.7GB.
