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 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.
Today, the Blu ray discs are yet another revolution in technology. 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 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.
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.
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.
