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

摘要

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 Tera bit/in2, the new study shows how the density could be increased to 10 Tera bit/in2 or more. Researchers have shown that they can get ultra-high densities without the need for ultra-sharp tips. Conventional storage technologies like magnetic hard disk drives are currently 'stuck' at just under 1 Tera bit/in2 densities and their road map does not predict reaching 10 Tera bit/in2 until 2015 in the lab and 2020 for production.
