Using nanotechnology, researchers have developed a technique to increase the data storage capacity of a DVD from a measly 4.7GB to 1,000 terabytes. Image: Nature Communications We live in a world where digital information is exploding. Some 90% of the world’s data was generated in the past two years. The obvious question is: how can we store it all? In Nature Communications today, we, along with Richard Evans from CSIRO, show how we developed a new technique to enable the data capacity of a single DVD to increase from 4.7 gigabytes up to one petabyte (1,000 terabytes). So how did we manage to achieve such a huge boost in data storage? The basics of digital storage Although optical discs are used to carry software, films, games, and private data, and have great advantages over other recording media in terms of cost, longevity and reliability, their low data storage capacity is their major limiting factor.
The operation of optical data storage is rather simple. Circumnavigating Abbe’s limit.
