Some promising news from the DVD standards front…
The electronics industry is in a fine mess, with two blue-laser disc standards (Blu-ray and HD-DVD) competing to succeed ordinary red-laser DVDs.
However, two top Warner engineers, Alan Bell and Lewis Ostrover, have been working on a cheaper and more elegant solution.
Blu-ray uses a 405-nanometre wavelength laser to read data from tracks 0.1-millimetres-deep on the top surface of a disc. HD-DVD, on the other hand, uses the same wavelength to read recordings at a depth of 0.6 mm.
