Cross License Agreement of Blue-Violet Laser Diode
related Patents for Optical Disc
Nichia Corporation (hereafter "Nichia") and Sony Corporation (hereafter "Sony") have come to an agreement on the cross license of Blue-Violet Laser Diode (hereafter Blue-Violet LD) related patents for optical disc use.
In December 2002, Nichia and Sony have agreed to collaborate on the development of Blue-Violet LD as well as building-up an environment to share the usage of the related technologies which the 2 companies possess, to accelerate the growing demand of Blue-Violet LD. Nichia and Sony have also worked in collaboration on the Blue-Violet LD development for optical disc recording/play-back use.
Blue-Violet LD is a 405nm wavelength semiconductor laser which will be vital for Blu-ray disc system, enabling digital recording of high-definition (HD) contents (movies) in consumer use and professional disc system XDCAM. It is the key device in the HD era, in various occasions where high quality images/movies are the key in HD contents creation in Digital HD broadcasting and recording/play-back in consumer use.
Through the cross-license, in addition to Nichia, which is most advanced on a world-wide basis as the Blue-Violet LD supplier, Sony will also mass-produce and be the supplier of Blue-Violet LD, leading to building-up a stable environment of the supply of Blue-Violet LD for optical disc use, required for Blu-ray disc system market which is expected increase significantly.
Both companies have agreed to continue to collaborate in technology development, leading to enhanced performance of Blue-Violet LD and contribution in the development of Blu-ray disc and XDCAM market.
