Japan finds new materials to manufacture low-priced 25TB high-capacity discs

AFP: A Japanese research team announced that they found a new material that could produce an astonishing volume of discs at a low price, theoretically up to 25TB.　　Shin-ichi Ohkoshi, a professor of chemistry at the University of Tokyo, explains that the material is a new form of titanium oxide, which can be converted back and forth between ferrous and Brown semiconductor states at room temperature when exposed to light, creating a switch closure function to store data.　　The greater the cautious one claims, it "has the hope of becoming the next generation of light storage equipment materials." His team has successfully used the material to produce particles with a diameter of only 5-20 nanometers. If you use the smallest of the particles, the produced CD can save a staggering 25TB of data, equivalent to 5,000 times the DVD, BD 1000 times.　　Of course, the corresponding data writing and reading devices must also be developed. Compared to the current DVD, BD burning discs used in germanium antimony tellurium alloy (are rare metals), the market price of titanium oxide is only about 1%. Big Yue said: "Do not worry about the resources of rare metals." Titanium oxide is both cheap and safe, and has been widely used in the production of flour, Bai and other products. "Of course everything is still at the theoretical stage, and the big one admits not knowing when to make a real disc," he added, adding that it would start a commercial feasibility study with private companies.
