    Date: 2010.01.13 | Category: Uncategorized | Tags: ,,,,

    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.  The BDA boasts 180 of the world’s leading consumer electronics, media and personal computer manufacturers.

    HD DVDs and Blue Ray DVDs were in fierce competition some time back over which would become the successor of the DVD.  With the results of blu ray discs being the winner, the attention has now been turned on the blu ray drives 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) 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. A single-layer HD-DVD disc only store 15 GB whereas single-layer blue ray DVDs can store 25 GB which is more than 2 hours of high-definition video and 13hours hours of standard 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. 

    Many online shopping websites are available for you to choose your blu ray drives.  A simple search will find you excellent 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 manufacture of backward compatibility reading normal compact discs and DVDs in addition to blu ray discs.
