A Million Little Pixels

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 happened to be the first instance of low-priced media which offered recordable, pre-recorded and rewritable options. It enabled widespread recording and distribution 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.

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.   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 fact that the blu ray discs are based on the bare disc physical form factor renders it compatible with compact discs and DVDs.

Just as its name denotes, blu ray discs utilizes a blue-violet laser beam to read and write data instead of the red laser beam which is being used as per the available technology at present. 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 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.
