Researchers at Flinders University have developed a novel polymer material that holds promise for efficient and sustainable high-density data storage. This low-cost material stores data as tiny 'dents' and can be erased and reused multiple times using heat.
A new material for high density data storage can be erased and recycled in a more efficient and sustainable way, providing a potential alternative to hard disk drives, solid-state drives and flash memory in future. The low-cost polymer stores data as 'dents', making a miniscule code in patterns, with the indents just nanometers in size -- promising to store more data than typical hard disk drives.
The new Flinders University Chalker Lab polymer, which can have the information in it wiped in seconds by short bursts of heat and be reused several times, is described in a major new article in the journal. 'This research unlocks the potential for using simple, renewable polysulfides in probe-based mechanical data storage, offering a potential lower-energy, higher density and more sustainable alternative to current technologies,' says first author and PhD candidate Abigail Mann, from the College of Science and Engineering at Flinders University. Made from low-cost materials, sulfur and dicyclopentadiene, the researchers used an atomic force microscope and a scanning probe instrument to make and read the indentations. Senior author Professor Justin Chalker says the development is the latest example of new era polymers capable of making a difference to a wide range of industries. 'The age of big data and artificial intelligence is increasingly driving demand for data storage solutions,' says Professor Chalker. 'New solutions are needed for the ever-growing computing and data storage needs of the information era'
