摘要： A ferroelectric recording medium and a writing method for the same are provided. The ferroelectric recording medium includes a ferroelectric layer which reverses its polarization when receiving a predetermined coercive voltage. A nonvolatile anisotrophic conduction layer is formed on the ferroelectric layer. A resistance of the anisotrophic conduction layer decreases when receiving a first voltage lower than the coercive voltage, and the resistance of the anisotrophic conduction layer increases when receiving a second voltage higher than the coercive voltage. Multi-bit information is stored by a combination of polarization states of the ferroelectric layer and the resistance of the anisotrophic conduction layer. Accordingly, multiple bits can be expressed on one domain of the ferroelectric recording medium.
