Method of reproducing information using semiconductor probe and device adopting the semiconductor probe

摘要

An information reproducing apparatus and a method using a semiconductor probe are provided. The information reproducing apparatus includes a semiconductor probe including a semiconductor tip including a channel varying with an electric field generated by an information recording medium; a modulator applying a high frequency modulation signal to the semiconductor probe to form a modulation electric field so as to modulate an information signal induced by the electric field; a signal detector detecting a signal generated by the semiconductor probe; and a demodulator extracting the information signal modulated by the modulation electric field from the signal detected by the signal detector.
