Japanese electronics giant Ricoh has developed a component that could bring the prospect of HD DVD and Blu-Ray compatible hardware being developed by manufacturers to life. The component in question is a diffraction plate. The component sits between the laser and the lens and adjusts the light beam so it focuses on the proper potion of the disc. The company claims it will allow both reading and writing to the disc formats.
The data layer on a Blu-ray disc resides 0.1 mm from the surface, whereas HD DVD's data layer is 0.6-mm deep. "This diffraction device is the first one that is ready for four formats, including BD and HD-DVD," claimed a Ricoh spokesman. "It will make it possible to build players and recorders ready for all formats, which will benefit consumers,"
Indeed it would benefit consumers, as the format war has put most consumers off the idea of investing in either HD DVD or Blu-ray due to fears the hardware will be obsolete in the near future. The war could be much worse than the VHS-Betamax situation, as with HD DVD and Blu-ray, you don't just keep movies in mind, you have to consider the issue even when buying a PC.
Ricoh will show the optical device at the International Optoelectronics Exhibition '06 outside Tokyo on July 12-14. The company intends to offer the device to OEMs by year's end.
