BIT RECORDING METHOD IN THE FERROELECTRIC MEDIA USING PROBE OR CONDUCTING STRUCTURE

摘要

A bit recording method in ferroelectric media using a probe or conductive structure is provided to apply base bias voltage between switching voltages so as to prevent changes in potential and record a small bit. A bit recording method in ferroelectric media comprises the steps of: contacting a probe with the surface of a recording medium and applying switching voltages to the recording medium and the probe for recording bits; and equalizing the potential of the probe and the potential of the recording medium surface to prevent a potential distortion by applying base bias voltage between the switching voltages, where the base bias voltage is a voltage between the negative switch voltage and the ground voltage when recording '0' bit, and a voltage between the ground voltage and the positive switching voltage when recording '1' bit.
