In the present day, the blu ray discs are the latest upheaval in technical know-how.  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 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.  Now that blu ray discs have won this battle, the focus is now on blu ray dvd burners that support the ability to read and write the data on blu ray disks.  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) 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 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 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.  

There are many online shopping avenues for selecting you blu ray drives.  A simple search will find you excellent bargain for your money. Some of the many manufactures of blu ray drives include BenQ, HP, LG, Panasonic, Philips, Pioneer, Samsung and Sony.  Though it is not obligatory, the Blu Ray Disc Association allows blue ray drive technology backward compatibility reading normal compact discs and DVDs in addition to blu ray discs.
