The HD-DVD vs Blu-ray battle resembles that between Betamax and VHS and DVD+RW and DVD-RW. Currently, major Hollywood film studios are split evenly in their support fro Blu-ray and HD-DVD, but most of electronics industry is currently in 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 suggests, uses a blue-violet laser to read and write data rather than a red one.
