About Blu Ray Discs
Co-published 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 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 increased the DVD’s popularity with the clients.
Today, the blu ray discs are yet another revolution in technology. 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 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 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.
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.
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.
