POSTER: computer news   ||   NICHIA BLUE-VIOLET LASER DIODE	DATE:2007-02-23
The Japanese company nichia corporation declared about the fact that it successfully completed the development of powerful blue-violet laser diode, which will make possible to attain the recording speed into 10x on two- and to 2x - to the four-layer disks of format from the following generation (HD DVD Blu-ray). The contemporary diodes, utilized in the present recorders of such sizes, emit light pulses with power in 130 mW, whereas in the development Of nichia this index is equal to 320 mW so high a power was achieved with the current strength in 260 mA and the voltage 5 v. the temperature of case diode did not exceed 80°C. In the course of tests the diode demonstrated stable work for the elongation of 1000 hours. Nichia speaks about the suppositional period of service of its solution in 10 thousand hours. The mass production of such diodes must begin in first half of 2008. This means that for the users on the market not later than the end of the following year can appear the high-speed drives, which record the disks HD DVD and Blu-ray. For this it would be however, increase rather well the service life of the service of such diodes.	NICHIA BLUE-VIOLET LASER DIODE
