Typical home-computer hard disk drives consume a lot of power and are limited to a few terabytes per drive. Optical storage media like DVD and Blu-ray are energy efficient and cheap, but storage densities are very low due to the planar nature of the discs and the ever-daunting optical diffraction limit. However, researchers have made inroads into developing a 3-D diamond chip that could store vastly more data than current technologies. https://phys.org/news/2016-10-defects-diamond-unique-platform-optical.html General Physics Wed, 26 Oct 2016 14:00:01 EDT news396679728 From the transparent cockpit canopy of fighter jets to everyday applications such as spectacle lenses and Blu-ray discs, polycarbonate plastics are valued for being light, strong and offering exceptional optical clarity.

It has developed the new method through the use of two-photon absorption in order to generate heat, and the report in TechOn! notes that this two-photon method is suited for multilayer discs. As the reaction caused by two-photon absorption can be limited to the small area of the focal point of a laser light, it is possible to increase the number of recording layers. The nuance is that Fujifilm has combined a two-photon absorption method with a "heat-mode recording" method. The latter refers to technology that makes the most of a phenomenon where a change is caused by applying a laser light with a high energy density to instantaneously increase the temperature of a minute area of a recording material. Two-photon absorption refers to the simultaneous absorption of two photons of identical or different frequencies to excite a molecule from one state to a higher energy electronic state. https://phys.org/news/2012-11-fujifilm-1tb-optical-disc.html Hi Tech & Innovation Sun, 18 Nov 2012 06:50:01 EST news272441852 High-definition TVs have officially graduated to Ultra HD. https://phys.org/news/2012-10-ultra-hd-tvs-figure-prices.html Consumer & Gadgets Fri, 26 Oct 2012 12:40:01 EDT news270470722 Businesses and consumers may soon have a simple, cheaper way to store large amounts of digital data.
