Sanyo develops blue-violet laser -- 54GB per disc side Sanyo has announced that it is developing next generation laser for optical storage that would double the storage capacity of 27GB per disc per side, currently available on Blu-Ray discs that use blue laser technology for recording (DVDs and CDs use red laser technology)
Sanyo's claims at this stage are extremely vague -- according to some news reporting, this would be a "dual layer" Blu-Ray and not a new technology, but this sounds highly unlikely to us, since we're talking about different laser wavelengths here. But Sanyo's plans are to demonstrate the first products by July this year and start mass production by end of the year.

This isn't exactly what world wanted at this point -- a new technology to stir the already-messed-up "next generation DVD" wars that are emerging between whopping four different formats. And all this is happening when the good olde DVD recordable markets are finally gaining ground despite format wars.

I'm happy, at least people will stop bitching about 4.36GB being enough to store their crappy film and the extras and the menus ;) Paul.
