Blu Ray Discs is Thought as the Revolution in Technology
In the early 1980’s, the world changed with the introduction of the CD. It offered excellent audio quality and its 650MB storage capacity was a great leap in data storage and retrieval. This happened to be the first instance of low-priced media which offered recordable, pre-recorded and rewritable options. It allowed extensive copying and sharing out of audio. Anyway, the necessity for greater storage capabilities grew in the nineteen nineties and resulted in the creation of the DVD which saw a five-fold increase of storage capabilities. Although it was a new technology, the new DVD format used the same form factor as the CD which facilitated the migration into the next generation format. This added to the DVD’s success with consumers.
Today, the blu ray discs are yet another revolution in technology. 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 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. The wavelength of a blue-violet laser (405nm) is way shorter than that of a red laser (650nm) and this has made it easier to concentrate the laser spot with superb accuracy. 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.
