Sony's Blue-Violet Laser the Future Blu-ray? 260
JoshuaInNippon writes "Japanese researchers from Sony and Tohoku University announced the development of a 'blue-violet ultrafast pulsed semiconductor laser,' which Sony is aiming to use for optical disks. The new technology, with 'a laser wavelength of 405 nanometers in the blue-violet region' and a power out put 'more than a hundred times the world's highest output value for conventional blue-violet pulse semiconductor lasers,' is believed to be capable of holding more than 20 times the information of current Blu-ray technology, while retaining a practical size. Japanese news reports have speculated that one blue-violet disk could be capable of holding more than 50 high-quality movie titles, easily fitting entire seasons of popular TV shows like 24. When the technology may hit markets was not indicated."

Yet Another Format War on the Way... (Score:4, Insightful)
Of course, as soon as Sony brings this to market, some other company, or group of companies, will unveil a competing product incompatible with Sony's, starting yet another format war. Too bad these guys can't just work together and agree on a common format and save us all time, money, and having to deal with dead formats (e.g. HD-DVD).

Or worse, we'd be walking around with 1Gbps wireless connections and we'd be streaming HD movies from YouTube.
So unless they've figured out how to cram like 1PB or even 1EB on an optical disc, they're walking down a blind alley.

History is easy to forget. DVD was around on the shelves for almost a decade before it hit mass consumption levels. Blu-ray will probably see the same time frames, and this update to the format will take years of research and development before it's even commercially viable.
Don't sweat it.

There's nothing wrong with physical discs, only that they're being overtaken by thumb-size USB flash drives for data storage, and are no longer an economical method of mass data storage. It's cheaper to buy whole hard drives and use those for archives than to use optical discs now.
If they'd get off their asses and make optical discs that can store 1 or even 10 TB, and make them cheap, then optical discs would be relevant again. Until then, forget it.

They were already there, hence it's automatically on topic. It's almost like saying "Sigh, here comes another Slashdot story..." which will inevitably relate to the much more important topic surrounding shark mounted lasers.
Hence, I'm happier with this Slashdot story because it's actually *more* on topic than usual.

We are, at least this media. It'll be as popular as SACD and DVD Audio, which is to say not at all. Ever notice how they could sell DVDs with about 1000 of those iTunes tracks, but they don't? This won't be used to sell more on one disc, it'll be to tell you that you need BeyondHD resolution and lossless 384KHz/48 bit audio for your bats because otherwise you'll miss the overtones. Looking at the encodes I see that even BluRay is often overkill. Outside of backwater countries like the US the connection speeds are ready too. It just doesn't seem like the TV and movie industry is ready, but well... it seems more and more people understand that it's possible anyway.

CDs use EFM Encoding [wikipedia.org] to store their data, DVD's use EFMPlus and BD's use 17PP [cdrinfo.com].
Having a faster switching laser may allow for the run lengths to be different. But that's just my best guess.

He never said the Sony Spec was to be the one to rule them all, but rather he suggested they all work together to make the next spec to avoid a format war.
I would like to append something to that request, set all the features in stone, so consumers wont have to worry about firmware upgrades or hardware upgrades every time someone says hey wouldn't it be cool if... and then puts it into production. Sure the PS3 can keep up with the evolving blu-ray specs but not every device can.
