Table salt multiplies hard disk space six times

Their new manufacturing process, involving simple sodium chloride, can boost the capacity of computer hard disks by six times.

The discovery was made by Singapore's national research institution the Agency for Science Technology and Research, in collaboration with the National 
University of Singapore and the Data Storage Institute.

The agencies 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.  More Read
