• Ferroelectric digital data recording and reproducing experiment was successfully demonstrated by using both tracking and error correction techniques. The relationship between off-track amounts of scanning probe and signal detection tolerances were evaluated. Tracking accuracy demanded for achieving Tbit/in.2 class high-density recording was estimated to be sub-nanometer range by using a ferroelectric recording/reproducing system with nanometer order position controller. Based on these results, a high-density of 258 Gbit/in.2 ferroelectric recording and reproducing of digital image file was performed by using one reproducing scan for one recorded track method.
