Blu Ray Drives
In the present day, the blu ray discs are the latest upheaval in technical know-how. 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 Blu Ray Disc Association consists of one hundred and eighty of the world’s prominent PC, Media and consumer electronics producers.
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. The blu ray technology, 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 feasible to focus the laser spot with superior precision. 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 HD-DVD can hold up to 30 GB whereas dual-layer blue ray DVDs can store 54 GB which is 4.5hours of high-definition video and more than 20hours of a standard video.
Anyhow, blu ray drives are undoubtedly dearer than other standard drives. Blu ray drives that can both read blu ray discs and burn DVDs are about 3 times the price of a standard DVD burner. Further, if you are on the look out for blue ray dvd burners that can burn blu ray media, the prices will be 10 times higher.
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. Although it is not compulsory, the BDA allows blu ray technology to permit backward compatibility -reading standard DVDs and CDs in addition to blu ray discs.
