Information media and method and apparatus for writing and reproducing information using the same

摘要

Provided are a method and an apparatus for reproducing information using a semiconductor probe. The apparatus includes a storage media including a ferroelectric recording layer which stores information by arranging a polarization direction of polarization domains of the ferroelectric recording layer and a physical recording layer disposed on the ferroelectric recording layer and whereupon information is written by forming pits in the physical recording layer, a semiconductor probe generating a composite signal including an electric field signal generated by an electric field variation of the ferroelectric recording layer of the storage media and a thermal signal generated by a temperature variation generated due to a variation in a shape of the physical recording layer, a signal detector detecting the composite signal from the semiconductor probe, and a demodulator demodulating the composite signal from the signal detector and extracting the electric field signal and the thermal signal from the composite signal.
