Real information data bits were written onto a ferroelectric medium in the form of the polarization direction of nano-domains. Local domain switching was carried out by applying a voltage pulse. Pulse voltage value was varied based on the polarization directions in the immediate environment to keep the bit size constant. As a result, writing and storing of real information data was demonstrated at a density of 1 Tbit/inch2 and a bit error rate as low as 1.8 10-2.
