Dr. Joel Yang of R & D center Singapore Institute of Materials found a way to fit even several times larger number of bits in the same area, as is the case today. It turns out that just add a bit of common table salt. How is that possible?

Hard disks are coated with tiny magnetic pellets, separated by a few nanometers, thus creating the island, formed in the process nanolitografii. Dr. Yang found that by adding to the process a little salt, you can repeatedly increase the recording density on the surface of the disk, because salt is used to produce better, although not smaller granules, which appropriately manipulated, can turn into a unit of information, instead of cake each other in the island.

A group of scientists led by Dr. Yang has already demonstrated the storage capacity of 1.9 terabit, zmieszczoną on the surface of 6.5 square centimeters. It is about 4 times more than current hard drives get. According to the researchers, using this method you can get up to 3.3 terabit per square inch, which will translate into a 18-terabyte hard drives!
