According to Nikkei Net Interactive, Ricoh has developed a diffraction plate to be placed between the reader's laser and lens, allowing it to change the beam's spot size according to the media, either being CD, DVD, HD DVD or Blu-ray. A Ricoh spokesperson commented, "It will make it possible to build players and recorders ready for all formats, which will benefit consumers." Ricoh Technologies will unveil its new optical device this week at the International Optoelectronics Exhibition '06 in Japan.
