Researchers: Salt may improve hard drives' capacities - Technology - GMA News Online - Latest Philippine News: "A common item like sodium chloride - table salt - can make computer hard drives cram data up to nearly six times their current capacities, Singapore researchers have found.
Dr. Joel Yang of the Institute of Materials Research and Engineering (IMRE) said salt can be added to a developer solution to produce the bits that hold data.
"The secret of the research lies in the use of an extremely high-resolution e-beam lithography process that produces super fine nano-sized structures. Dr. Yang discovered that by adding sodium chloride to a developer solution used in existing lithography processes, he was able to produce highly defined nanostructures down to 4.5 nm half pitch, without the need for expensive equipment upgrades," the Agency for Science, Technology and Research (A*STAR) said.
