Scanning Nonlinear Dielectric Microscopy (SNDM) is the method for observing ferroelectric polarization distribution, and now, its resolution has become to the sub-nanometer order. Up to now, we have studied high-density ferroelectric data storage using this microscope. In this study, we selected stoichiometric LiTaO3 (SLT) single crystals as ferroelectric recording media. At first, we studied polarization inversion characteristics in detail, and as a result, we achieved forming small inverted domain with the radius of 6 nm. And we also studied the retention of inverted domain. Moreover, in a recent study, we have also formed inverted domain in congruent LiTaO3 (CLT) single crystal, and, as a result, we achieved high-density data storage in excess of 1 Tbit/inch2.
