Sharp Corporation announced during the Autumn Meeting of the Japan Society of Applied Physics that it managed to evolve in Blu-ray laser by developing a Blu-ray laser diode that works at 500mW at its peak. This is sufficient to burn 4-layer Blu-ray discs meaing that if the company`s product is approved by the BDA (Blu-ray Disc Association) we will be able to find on the market Blu-ray discs of 75 gigabytes or 100 gigabytes memory.

The electronic company discovered that the abilities of a diode increase faster, in an exponential rhythm, by getting an oxynitride separator between the dielectric foil and the crystal of the diode. After this discovery, the company put the findings to the test. Thus, the organization tested the working diode for 1000 hours at 176 degrees Fahrenheit at its peak power and concluded that the product is prepared for mass-production.

All that remains now is for Sharp Company to receive the approval of the Blu-ray Disc Association to commercialize Blu-ray discs of 75 gigabytes and 100 gigabytes, in order to start producing the discs.
