Packing in six times more storage density with the help of table salt

-- Dr Joel Yang from the Institute of Materials Research and Engineering , a research institute of Singapore’s Agency for Science, Technology and Research, with collaborators from the National University of Singapore and the Data Storage Institute has developed a process that can increase the data recording density of hard disks to 3.3 Terabit/in2, six times the recording density of current models. The key ingredient in the much enhanced patterning method that he pioneered is sodium chloride, the chemical grade of regular table salt.
