Technology of Blu Ray Drives
Today, the blu ray discs are yet another revolution in technology. The blu ray disc is the latest optical disc format created by the BDA (Blu Ray Disc Association which includes TDK, Thomson, Sharp, Pioneer, Philips, Mitsubishi, Sony, JVC, Panasonic, Samsung, Apple, Hitachi, LG, Dell, and HP. The BDA boasts 180 of the world’s leading consumer electronics, media and personal computer manufacturers.
In the past, High Definition DVDs and Blu Ray Discs were competing intensely about which would succeed the DVD. With the results of blu ray discs being the winner, the attention has now been turned on the blu ray drive that will operate the blu ray discs. As the name signifies, the blu ray technology makes use of blue-violet laser to access data whereas the available technology at present uses a red laser. A blue-violet laser (405nm) which is very short in wavelength than a red laser(650nm)concentrates the laser spot with superb accuracy. The plus point of this is that it allows data to be recorded in less space as the data can be stored compactly which gives the users to squeeze in more data on the disc though the size of the disc is akin to that of a CD/DVD. One single-layer High Definition DVD disc holds only 15 GB whilst single-layer blu ray disc can hold 25 GB which is over 2 hours of HD video and thirteen hours of normal video.A dual-layer High Definition DVD can store up to thirty GB whilst the same format blu ray DVDs can hold fifty-four GB which comes to about 4.5 hours of HD video and more than twenty hours of standard video.
However, blu ray drives are no doubt more expensive than its counterparts. Blu ray drives that can read blu ray discs as well as burn DVDs are about three times the price of standard DVD burner. And, if you want a blue ray burner that will burn the blu ray media, the price increases ten times more.
Many online shopping websites are available for you to choose your blu ray drives. A little research will enable you to find good bargain for your money. Several of the producers of blu ray drives are Sony, Samsung, Pioneer, Philips, Panasonic, LG, HP, and BenQ. Though it is not obligatory, the Blu Ray Disc Association allows blu ray burner technology backward compatibility reading normal compact discs and DVDs in addition to blu ray discs.
