| Abstract(in English) | The authors are studying ferroelectric probe memory using scanning nonlinear dielectric microscopy (SNDM) method as a reproduction technique to realize a next generation super high-density data storage system. We already demonstrated the possibility of ferroelectric data storage in excess of 1 Tbit/inch^2 using a congruent LiTaO_3 (CLT) thin crystal plate as a recording media. In this paper, the ferroelectricity of CLT was investigated more precisely, and very high-speed switching characteristic of nano-second order was successfully found out. This characteristic is also suitable for ferroelectric recording media as well as the characteristic of higher storage density. We also performed quasi-digital data recording experiments. Digital signal was recorded with the density of 726 Mdpi in CLT media, and the recorded digital signal was well reproduced by a single scan of a probe. |
