Why Blu Ray is called Blu Ray
About Blu Ray Discs
Sent by: Neoprene PC Adapter Cases. 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 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. 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 perfect definition of the ultimate user experience and allows the recording, rewriting, playback and distribution of high-definition videos.
The blu ray discs have been founded on the bare disc physical form factor which makes it compatible with CDs 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.
