Sony's high-capacity blue laser DVD recorder, set to debut in the United States this fall, crams five times more information on a
disc than the standard red laser version does and heralds the arrival of next-generation technology. Enthusiasts eager to get their hands on that much data capacity, however, may think twice after learning that production snags boosted the DVD's price to about $3,500. But researchers at BlackLight Power in Cranbury, New
Jersey, say they have made a discovery that may help overcome technical hurdles and get reliable blue lasers to market.
