Sharp to begin volume production of 210-mW blue-violet laser diodes

15 March 2007 19:14 by James "Dela" Delahunty | 1 comment

Sharp Corporation has announced it will begin of the High-Power Blue-Violet Laser Diode GH04P21A2G that achieves a power output of 210 mW, the industry's highest power output, in May. This device will enable high-speed 6X recording on next-generation dual-layer Blu-ray Discs (BD) and HD-DVDs.

This year, the market for recorders and PCs capable of recording on next-generation DVDs is expected to take off in earnest, and demand for blue laser diodes, the key device in this type of equipment, is projected to increase in tandem. Users are also expected to demand faster recording times in the future which will require speeding up the write process for individual layers on these discs.

Since beginning mass production of the industry�s first infrared laser diode for use in CD players in 1982, Sharp has consistently been an industry leader in both technology and production. The GH04P21A2G makes full use of crystal growth technology developed for infrared, red, and blue-violet low-power laser diodes. In addition to a newly developed laser chip with a proprietary facet structure and a high power output of 210 mW that will contribute to high-speed recording for the next generation of DVDs, this current device also features a long service life of 10,000 hours, a level that leads the industry.

We just might see the second gen equipment by X-Mas, Yehhhh! I'd love to be able to burn at 6x or 10x this could drive me to go get a new burner/player even if the price tag is still a bit high. [ + quote]
