"Racetrack memory, which reconfigures magnetic fields in innovative ways, could supplant current methods of mass data storage, such as flash memory and disk drives, due to its improved density of information storage, faster operation, and lower energy use," says Yassine Quessab, a postdoctoral fellow at New York University's Center for Quantum Phenomena (CQP) and the lead author of the work, which is reported in the journal Scientific Reports.

"While additional development is necessary in order to deploy them in consumer electronics, this pioneering type of memory may soon become the next wave of mass data storage," adds NYU Physics Professor Andrew Kent, the paper's senior author.
