New probe memory could achieve user densities over 10 terabits per square inch

Researchers have proposed a new strategy for writing data for scanned-probe memories with user densities that are potentially more than twice as high as those achieved with conventional approaches. While previous research has shown that scanned-probe memories have the potential to achieve storage densities of up to 4 Tbit/in², the new study shows how the density could be increased to 10 Tbit/in² or more.
