Abstract
The record condition extraction system () of a dielectric recording medium is intended to obtain an applied voltage and an applied time length to be recorded when recording information in the dielectric recording medium. The record condition extraction system () is provided with: an applied voltage setting device (); an applied time length setting device (); a record control device (); an applied voltage/applied time length record device (); a record device (); a dot radius measurement device (); a dot radius record device (); an optimum dot radius detection device (); a record condition determination device (); and an output device (). The applied voltage setting device () and the applied time length setting device () set a voltage and a time applied to a probe () of the record device (), respectively. The dot radius of a polarization domainwhich is recorded at the record device (), is measured at the dot radius measurement device (), and the optimum polarization domain () is obtained at the optimum dot radius detection device (). The applied voltage and the applied time length which have formed the polarization domain () are extracted as an optimum record condition.
