Researchers from Flinders College, the College of New South Wales (UNSW) Sydney, and the College of Adelaide have developed a brand new polymer that, they are saying, may ship a giant increase for high-density knowledge storage — by encoding values by depth.
“This analysis unlocks the potential for utilizing easy, renewable polysulfides in probe-based mechanical knowledge storage, providing a possible lower-energy, greater density and extra sustainable different to present applied sciences,” says first writer Abigail Mann, a PhD candidate in Flinders College’s Faculty of Science and Engineering, of the crew’s work and its potential influence — at a time when the calls for of the substitute intelligence (AI) growth put ever-growing pressure on storage, compute, and power sources.

“The age of huge knowledge and synthetic intelligence is more and more driving demand for knowledge storage options,” provides senior writer Justin Chalker. “New options are wanted for the ever-growing computing and knowledge storage wants of the knowledge period. Options are being sought to exhausting disk drives, solid-state drives and flash reminiscence that are constrained by knowledge density limits – or the quantity of knowledge they’ll retailer in a selected space or quantity.”
The crew’s polymer works, within the easiest phrases attainable, slightly like a traditional punchcard: reasonably than magnetic flux, like a standard exhausting drive, knowledge is encoded as bodily indentations — although at a a lot smaller scale than your traditional 80-column card. Fairly than merely recording knowledge as as to if there may be an indentation at a selected location, although, the system developed by the crew permits a single “bit” to retailer a number of attainable values by various the depth of the indent.
“Beautiful management of indentation depth is feasible over 1-30nm,” the researchers clarify. “This management allows knowledge encoding not simply as a perform of the presence or absence of an indent, but in addition indentation depth. This ternary coding will increase the info tensity fourfold over binary coding. Moreover, the coding will be finished at room temperature which is uncommon for mechanical info storage.”

The polymer developed by the crew has different benefits, too. One is that it is low-cost to make, utilizing readily-accessible sulfur and dicyclopentadiene; one other is that it may be cleaned in seconds by way of the applying of warmth, and reused a number of occasions. The one actual roadblock to its broad adoption: at current, knowledge is saved and browse utilizing a probe guided by an atomic power microscope — not the most affordable piece of apparatus, and never one thing you’ll be able to shrink down to slot in your common laptop computer.
The crew’s work has been revealed within the journal Superior Science below open-access phrases.
