Blu-ray : A Primer.

The HD-DVD vs Blu-ray battle resembles that between Betamax and VHS and DVD+RW and DVD-RW. Now , the major Hollywood film residences are split uniformly in their support fro Blu-ray and HD-DVD, but the majority of the electronics industry is now in the Blu-ray camp. The key difference between Blu-ray disc players and recorders and current optical disc technology is that Blu-ray, as its name advocates, uses a blue-violet laser to read and write information instead of a red one. Blue light has a shorter wavelength than red light, and according to the Blu-ray Disc organisation ( BDA ), which is made from, among others, Sony, Philips, Panasonic, and Pioneer, this suggests that the laser spot can be focussed with larger precision.

In Japan, they cost equivalent to $2000.
