Optware in Tokyo is really hoping that while other companies squabble over HD-DVD and Blu-Ray, their HVD will be available at the end of the year (

Latest word is that CMC Fuji Photo, CMC Magnetics and three other companies have jumped in to support Optware's HVD disc. (

Sadly, the latest news about this technology is from 2005.

I may well be wrong, but the diagrams of this technology look a bit like a scam. The technology alleges to allow red lasers to pass beyond blue-green lasers through different layers. Blu-Ray is so successful because the wavelength of blue laser is smaller than that of red; so how exactly would red pass beyond blue? It should be, I think, the other way around for it to actually work.
Da Programmer, please note that when technology hits a high, lots of fakes jump on board - remember Gizmondo's one-off hand held game player? They made millions upon millions on a bunk product designed only to ride a technology high.
