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.

In the past, High Definition DVDs and Blu Ray Discs were competing intensely about which would succeed the DVD. Now that blu ray discs have won this battle, the focus is now on blu ray drives that support the ability to read and write the data on blu ray disks. 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) has a far shorter wavelength than a red laser (650nm) making it feasible 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. 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.
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 blu ray drives that will burn the blu ray media, the price increases ten times more.
