摘要：
A recording/reproduction of information is effected using a probe electrode arranged to oppose a recording medium. A distance between the probe electrode and the recording medium is controlled by applying a voltage therebetween. A current flowing through the probe electrode upon application of the voltage is detected while the scanning is performed with the probe electrode over the recording medium. A correlation between a signal output according to the current detection and a reference signal is obtained to produce a reproduction signal from which a noise component due to an influence of an atomic step present on a surface of the recording medium is removed. The reproduction of information is effected in accordance with the generated reproduction signal.
