Abstract
A ferroelectric storage apparatus includes: a ferroelectric recording medium; a conductive probe configured to write information to and read information from the ferroelectric recording medium; a probe slider configured to cause the conductive probe to travel by floating above a surface of the ferroelectric recording medium; a ferroelectric recording medium driver configured to rotate the ferroelectric recording medium; and a recording-and-reproduction signal processor configured to process a write signal and a read signal of information transmitted to and received from the conductive probe. The conductive probe includes: a base body constituted by a conductive material; an insulating layer formed on the base body and includes a through hole: and a needle-shaped electrode formed in a cone shape on the base body in the through hole. A portion of the needle-shaped electrode protrudes from a surface of the insulating layer.
