“The restricted storage time of present storage media requires information migration within numerous years to avoid any data loss. These defects are inflicted by a focused beam of protons or helium ions and read using luminescence systems associated to the defects.Traditional storage gadgets throttled by physicsCurrently, magnetic memory is the prime choice when it comes to data storage services aiming for large capabilities, while the laws of physics set the limits to attainable storage densities. Changing to electron-beam excitation rather of optical excitation for the data read-out, the limitation achievable in this way corresponds to a currently reported record areal storage density of a model magnetic tape, which has, nevertheless, much shorter storage time and higher energy consumption.Reference: “Ultralong-Term High-Density Data Storage with Atomic Defects in SiC” by M.

“The limited storage time of present storage media needs information migration within several years to prevent any data loss. These defects are inflicted by a focused beam of protons or helium ions and read utilizing luminescence systems associated to the defects.Traditional storage devices throttled by physicsCurrently, magnetic memory is the prime option when it comes to data storage options intending for large capacities, while the laws of physics set the limits to attainable storage densities. With near-infrared laser excitation, modern-day encoding techniques and multi-layer information storage, namely the stacking of up to ten silicon carbide layers on top of each other, the group reaches an areal storage density that corresponds to that of Blu-ray discs. Changing to electron-beam excitation instead of optical excitation for the information read-out, the limit possible in this manner corresponds to a presently reported record areal storage density of a model magnetic tape, which has, nevertheless, much shorter storage time and greater energy consumption.Reference: “Ultralong-Term High-Density Data Storage with Atomic Defects in SiC” by M.
