Table salt increases data storage density

Table salt increases data storage density

“Scientists at Singapore’s Agency for Science Technology and Research have upped the storage densities of hard drives – with humble table salt.

Traditionally, hard disks use randomly distributed nanoscopic grains about seven to eight nanometres in size to hold data, with a cluster of a few tens of grains holding one bit.

But the scientists – led by Dr Joel Yang – were able to add table salt to the extremely high-resolution e-beam lithography process to make grains that could hold a single bit of data, while measuring 10 nanometres.
The salty solution

The result is a super-dense form of storage that could see huge hard drives manufactured using existing processes, with today’s one terabyte drives holding six times as much data.”
