Blu-ray innovator Sony has teamed up with scientists at Tohuku Univsersity in Japan to develop a new blue-violet laser that could enable Blu-ray discs to reach one terabyte (1TB) capacity.

In a press release clearly aimed at the technically-minded, Sony revealed it has successfully developed an 'all-semiconductor laser picosecond pulse source' with a wavelength of 405 nanometers.

'It is capable of generating optical pulses in the ultrafast duration of 3 picoseconds, with ultra-high output peaks power of 100W, which is more than a hundred times the world's highest output value for conventional blue-violet pulse semiconductor lasers,' said the CE giant.

The technology would allow Sony to increase the density of data on a single layer of a BD by as much as 20 times, according to the number crunchers at Japanese newspaper The Daily Yomiuri. This will be of immediate interest to home cinema hedz, as hitherto unimaginable possibilities – an entire season of Lost on one disc, for instance, or the Star Wars Trilogy on a single platter – become tantalisingly real. Unfortunately, there's no word on when 1TB Blu-rays, either for domestic or commercial use, might appear,

The breakthrough follows the recent news that the Blu-ray Disc Association has approved the BDXL format, which delivers recordable discs with up to 128GB capacity.

Wow a terabyte, that's pretty awesome.

That would be great to back up your HD but it would cost alot of money for one of those DVDs maybe they should develope stronger DVDs ie there thicker and scratch resesident and maybe even anti laser burn just a thaught.

Is anyone else questioning just exactly how long it would take to burn a tb to a disk?

takes me 10 min to burn 100mb to a disc with a 44x cd burner.....

It takes me around 5 mins to burn a 4.7 GB disk full so it will probably take around 5-10 hours

I agree with you, it would be nice to have stronger DVD's that are scratch resistant.
