Burning Blu-Ray Discs at 10X
Nichia, a Japanese company, developed a blue-violet semiconductor laser diode, featuring a power high enough for burning Blu-Ray and HD DVD media at 10X.
According to Nichia the new laser diode is able to emit pulsed light at 320mW, while it offers a stable operation of 1,000 hours. The diode could be used for optical discs including Blu-ray and HD DVD, allowing 10X speed recording with a double-layer disc and 2X speed recording with a four-layer disc. Currently blue-violet semiconductor laser diodes offer a pulsed output of 130 mW.
Mass production units should start in the first half of 2008.
This is a good news for the HD formats who will need that kind of technology to succeed in the data storage market. Blu-ray and HD DVD movies are going to hit our living rooms like a storm in the next 18 months but nothing is clear about the ability of the HD formats to impose themselves to IT people. 10X burning is a minimum we should expect from the blue-violet technologies.<
