A new method of achieving real information recording with a density above 1 Tbit/in.2 using servo tracking control in ferroelectric data storage systems is proposed. In this system, position control of the read/write head was realized by the scanning nonlinear dielectric microscopy technique. The data bits can be read by only one-line scanning on a one-line data track using high-precision head position control. The tracking accuracy of this system was evaluated to be about 2 nmpp. As a result, actual data composed of 64 × 64 bits were recorded at an areal density of 1 Tbit/in.2 and the bit error rate was evaluated to be 1.7 × 10-3.
