Get more from: Neoprene iPod Cases. Blue ray discs are the latest breakthrough 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 Blu Ray Disc Association comprises one hundred and eighty of the globe’s frontline PC makers, media and consumer electronics producers.
As the name suggests, the blue ray discs make use of a blue-violet laser to read and write data as opposed to the current technology which uses red laser. A blue-violet laser (405nm) possesses very shorter wavelength than a red laser (650nm), thus enabling the focusing of the laser spot with exceptional accuracy.
The plus point of this is that it allows data to be held in smaller space as the data could be squeezed in compactly which in turn allows the user to store extra data on the disc even though the disc is more or less the same size as a compact disc or a DVD. Additionally, blue ray discs offer a large storage capacity. A single-layer blue ray disc can store up to 27GB of data which is more than 2 hours of high-definition video and 13hours hours of standard video. The dual-layer blue ray disc can store 50GB of data which is 4.5hours of high-definition video and more than 20hours of a standard video.
Blue ray discs are the perfect definition of the ultimate user experience. It additionally permits the rewriting, recording, playing and distribution of HD videos. The blue ray discs have been founded on the bare disc physical form factor which makes it compatible with CDs and DVDs.
Blue ray discs are also light on the manufacturers since these are built by injection-molding process on a single 1.1-mm disc compared to the traditional which thereby reduces costs.
The costs thus saved are spent on the addition of the shielding layer necessary on blue ray discs with the result that the end price being more or less the same as that of a DVD. Blue ray discs also boasts of an advanced data transfer rate of thirty-six Mbps over the present-day DVDs that does the data transferring @ ten Mbps. The meaning of this is that it takes just an hour and half to burn twenty-five GB of data onto a blue ray disc.
Originally, the existing conventional DVDs and compact discs were introduced with just read-only formats. The blue ray discs however, plan to provide a wide range of formats that include BD-ROM (read only), BD-R (recordable) and BD-RE (rewritable).
