With the advent of the Compact Disc at the beginning of Nineteen Eighties, the world underwent a dramatic change. 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 allowed extensive copying and sharing out 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. 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. The BDA boasts 180 of the world’s leading consumer electronics, media and personal computer manufacturers.
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 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.
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. 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.
