Fujifilm, the multinational imaging company.
Fuifilm has a research team working on a new recording method for multilayer optical discs, that uses two-photon absorption to generate heat to bring a one terabyte optical disc.
Making a combination of this method with heat-mode recording, the researchers used the technology to apply a laser light with a high energy density to instantaneously increase the temperature of a minute area of a recording material.
Thus making multilayer recording of up to 25 Gbytes per layer possible. We all love Blu-rays with 25 GB capacity that take care of most of our data. But with this tech on the verge, we are looking at an additional 20 layers per side of a disc, so what we get is a one terabyte storage capacity. And Fujifilm says that this kind of a storage capacity may come to the market of discs by 2015.
