New tech for next-gen DVDs
Japanese Nichia Corp. has developed a blue-violet semiconductor laser diode, featuring a power high enough for burning Blu-Ray and HD DVD media at high speeds.
Nichia’s new laser diode is able to emit pulsed light at 320mW, while it offers a stable operation of 1,000 hours, according to the company. 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.
