Table salt used to boost digital storage

SINGAPORE: Scientists in Singapore said they have discovered a process that can expand the data storage capacity of computer hard disks six-fold using a common kitchen ingredient – table salt.The discovery was made by Singapore’s national research institute the Agency for Science, Technology and Research, in collaboration with the National University of Singapore and the Data Storage Institute.
The institutions have "developed a process that can increase the data recording density of hard disks to 3.3 Terabits per square inch, six times the recording density of current models", they said in a statement.
"This means that a hard disk drive that holds 1 Terabyte (TB) of data today could, in the future, hold 6 TB of information in the same size using this new technology."
Scientists were able to boost data storage capacity by packing more bits – miniature structures which hold information – in neater patterns compared to the random configurations used in current hard disk drives.
"It’s like packing your clothes in your suitcase when you travel. The neater you pack them the more you can carry," the statement said.
The method – called bit patterning – had previously not been feasible as scientists were unable to see the outlines of the bits clearly after they had been printed onto a film in a process much like developing photographs
But "adding table salt into the solution used for bit imaging allowed the outlines to stand out in sharp relief which allowed them to see the fine lines which were normally blurred",explained by Joel Yang, the Singapore scientist who discovered the salty recipe.
