It is indispensable to reduce the friction between a ferroelectric recording medium and probe tips, and to eliminate the wear of tips to improve reliability toward the practical use in the ferroelectric probe memory (FPM) we are studying. Perfluoropolyether (PFPE) lubricant of 20 nm thickness was spread uniformly on a congruent LiTaO3 (CLT) ferroelectric recording medium as one of the measures against friction and wear. We conducted a polarization domain measurement and a dot array recording experiment with the lubricated CLT where frictional forces were reduced by 70%. The polarization signals of the medium were successfully measured with a high signal-to-noise ratio and recorded as dot arrays of 1.2 Tbit/in.2 density through the lubricant.
