Sharp aims for 8X Blu-ray laser diode by 2010

In a technological briefing held in Japan, Sharp revealed some of its plans relating to Blu-ray laser diodes. The company is a pioneer in the field after mass-producing the industry's first infrared laser diode for use in CD players in 1982. Sharp showcased its latest High-Power Blue-Violet Laser Diode for Blu-ray recorders that could achieve 6X writing speed.

Two variations of the diode will begin mass-production next month; the GH04P25A4G which is suitable for notebook PC Blu-ray drives and the GH04P25A2G which can be installed in Desktop Blu-ray writers. Both have a power output of 250mW. However, the more enthusiastic news came when Sharp revealed its post-6X plans.



The company is developing a 300mW laser diode that will be capable of recording Blu-ray discs at 8X speed. This will likely reach mass-production in 2009 with a future planned diode with a power output of 400mW possibly in line for mass production in 2010.

  I'd buy that... 8X will be good enough for a LONG time... Sure, my DVD burner burns at 16x but I still burn all my DVDs at 4x to be safe...

  8x blu ray > 8x dvd > 8x cd
  
  8x blu ray will transfer data faster than 8x dvd.

  well here some read write specs.
  
  
  For a CD, 1x = 150 KiB/sec
  For a DVD, 1x = 1.385 MiB/sec (1.32 MB/sec)
  
  [HD DVD: 1x = 4.57 MiB/sec (4.36 MB/sec)]
  [Blu Ray: 1x=6.74 MiB/sec (6.43 MB/sec)]
  
  [MiB = mebibyte, or mega binary byte. Equals 2^20 Bytes

  How about working on lowering the costs to consumers for Blu-Ray burners, then work on increasing the writing speed?.
