subject: Blu Ray Discs: Provide An Increase In Storage Content [print this page] In the early 1980's, the world changed with the introduction of the CD. It provided great audio quality and the ability to hold six hundred and fifty megabytes of data as a giant step in data storing and retrieving. This was the first time people had access to pre-recorded, recordable and rewritable media at low costs. It enabled widespread recording and distribution of audio. You can consider blu ray discs.
However, in the 1990's, the demand for higher storage capacities arose and led to the development of the DVD which was a 5 - 10 x increase in storage capacity. Even though the know-how was novel, the latest DVD format made use of the same form factor as the Compact Disc that made easy the transformation to next generation format. This increased the DVD's popularity with the clients. And the new generation comes with blu ray discs.
In the present day, blu ray discs have made still another upheaval. This new optical disc format is a proud development of the Blu Ray Disc Association (BDA) that include HP, Dell, LG, Hitachi, Apple, Samsung, Panasonic, JVC, Sony, Mitsubishi, Philips, Pioneer, Sharp, Thomson, and TDK. The BDA boasts 180 of the world's leading consumer electronics, media and personal computer manufacturers.
Blu ray discs offer an increase in storage capacity with its 25GB on a single-layer disc to its 50GB on a dual-layer disc. It is the perfect definition of the ultimate user experience and allows the recording, rewriting, playback and distribution of high-definition videos. The fact that the blu ray discs are based on the bare disc physical form factor renders it compatible with compact discs and DVDs.
The blu ray discs, as the name suggests, uses a blue-violet laser to read and write data unlike the current technology which uses red laser. A blue-violet laser (405nm) has a far shorter wavelength than a red laser (650nm) making it possible to focus the laser spot with superior precision. The advantage of this is that, it permits data to be stored in less space since the data can be packed more tightly, which further, allows consumers to fit additional data on the disc even though it may be the same size as a CD or a DVD.
Several of the world's prominent PC and video game makers, recording media and consumer electronics and music companies have taken up this technology today and Hollywood studios and various smaller studios have already taken interest in these latest blu ray discs with the results of some of them already announcing the release of their new flicks on blu ray discs.
