Why Blu Ray is called Blu Ray

More at: Neoprene PC Adapter Cases. 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.  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.  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.

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 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 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.
