A team of scientists from the Tohoku university in Japan has partnered with Consumer electronics giant Sony to develop a blue-violet laser that could one day burn 1TB Blu-ray discs.
That's roughly 20 times more than today's Blu-ray blank disks and would be enough to backup those multi-terabyte hard disk drives.
The Examiner reports that the laser has an output of 100W which is 100 times more powerful than the "world's highest output values for conventional blue-violet pulse semiconductor lasers."
It can apparently generate beams of light of 405nm, which is at on extreme of the electromagnetic spectrum, and last for only 3 picoseconds.
Other Japanese firms, such as Sharp, have developed 100GB BDXL discs which cram more layers per blank disks while Sony's route is to get higher bit density on one layer.
Ultimately, combining both technologies could mean multi-terabyte Blu-ray disk until the first generation of consumer grade 3D holographic storage makes them all obsolete.
Regardless, with more and more content being stored in the cloud, the very future of onsite, physical storage may well be at stake although 1TB is a heck lot of data to transfer.
