Blu Ray Discs Offer an Increase in Store Content
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 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. 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 added to the DVD’s success with consumers.
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.
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 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.
Presently supported by some of the world's leading consumer electronics, personal computer, video game, recording media, and music companies, these new generation blu ray discs have also won the support of Hollywood studios and other smaller studios, some of whom have already announced the release of new movies on blu ray discs.
