In You could never have imagined that the humble table salt can enable you to store more data in your hard disks. Scientists have discovered a new manufacturing process, which involves sodium chloride, and can boost the capacity of computer hard disks by six times.
The scientists at Singapores Agency for Science Technology and Research have collaborated with the National University of Singapore and the Data Storage Institute for making this landmark discovery. Dr Joel Yang is the leader of the team.
In a statement released to the media, the scientists said, We 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.
The addition of sodium chloride to the manufacturing process meant the pattern of bits units of information on the surface of each magnetic disk was neater, allowing more to be crammed in. The salt improved the resolution of the electron beam used to print the bits.
Dr Joel Yang said, It can give you a very high contrast. We are now able to see fine lines that would normally be blurred out. Otherwise you can try your best to pattern these bits very closely but they will all end up being gigantic blurred out blobs.
The process is expected to be ready for commercial use by 2016.
