The Nichia Corporation has announced that they've developed a high power blue-violet laser diode for Blu-ray Disc and HD DVD recording. According to their press release, the new diode can write to dual layer media at speeds up to 10x and quad layer media at 2x.
Nichia Corporation succeeded in developing high power blue-violet semiconductor laser diodes corresponding to a double-layer disc at more than 10 X record speed/ a quad-layer disc at more than 2 X record speed applied for the next generation DVD recorders.
We confirmed that estimated life time exceeded 10,000 hours and stable operation was achieved for 1000 hours with the condition of 320 mW pulsed operation at 80°Ccase temperature.
While quad layer media is aways off, this new diode should help boost the recording speed of Blu-ray and HD DVD writers. More information can be found on Nichia's website.
