It is anticipated that, in the near future, all information in the physical world will be recorded and analyzed by advanced artificial intelligence. To enable such data collection and analysis, it is essential to develop next-generation ultra-high-density recording devices capable of recording and reproducing information at densities and speeds far exceeding those of current magnetic hard disk drives (HDDs).
With this backdrop, we have been conducting research and development on next-generation ultra-high-density ferroelectric HDDs (Fe-HDDs; SNDM probe memory). Conventionally, data writing and reading in SNDM probe memory have been performed by bringing the probe tip into contact with the ferroelectric recording medium; however, the practical application of Fe-HDDs requires contactless writing and reading, similar to conventional magnetic HDDs. Therefore, in this study, we applied a non-contact SNDM (NC-SNDM) method with atomic resolution and conducted experiments on non-contact writing and reading in Fe-HDDs.
