With Help Of: Neoprene PC Adapter Cases. With the advent of the Compact Disc at the beginning of Nineteen Eighties, the world underwent a dramatic change. It offered excellent audio quality and its 650MB storage capacity was a great leap in data storage and retrieval. 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. 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 added to the DVD’s success with consumers.

In the present day, blu ray discs have made still another upheaval. This novel optical disc system is an important creation of the Blu Ray Disc Association (BDA) which includes Dell, Hp, Hitachi, LG, Samsung, Apple, JVC, Panasonic, Mitsubishi, Sony, Pioneer, Philips, Thomson, Sharp and TDK. (The BDA boasts 180 of the world’s leading consumer electronics, media and personal computer manufacturers| Blu Ray Disc Association consists of the Globe’s frontline producers of media, personal computers and consumer electronics items, numbering one hundred and eighty.

Blu ray discs provide enhanced storing capabilities, i.e. twenty-five GB on single-layer and fifty GB on dual layer discs. It is the last word in user experience and facilitates rewriting, recording, playback and distribution of HD videos.

The blu ray discs have been founded on the bare disc physical form factor which makes it compatible with CDs 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 plus point in this is that it allows storing of data in very little space compactly giving the user extra space to add more data even though the size of the disc is similar to that of a normal CD/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.
