Sony, university create tech for 1TB Blu-rays
Researchers at Sony together with those at Japan's Tohoku University said they have developed a blue-violet laser that can create 1TB Blu-ray discs. The ultrafast pulsed semiconductor laser has a laser wavelength of 405 nanometers and can generate optical pulses just the picoseconds in duration. Moreover, the new laser doesn't require a large light source and a specialist technician to operate, as required in the past with similar technology.
Sony says it has tested the new storage, and will continue to develop it to create next-generation disk storage devices. Currently, Blu-ray drives hold 25GB of data, with dual-layer versions capable of storing 50GB. Sharp and TDK recently put out new 100GB BDXL discs, though these simply use four regular layers rather than higher density on existing layers.
There is no indication of when the new discs and writers will be commercially available, or what they will initially cost. [via Examiner]
