Abstract

PURPOSE:To perform recording and reproduction with high density and high accuracy, by performing the position detection and the position control of a probe electrode by detecting the relative displacement of the reference scale of a recording medium having the reference scale set as reference in a plane and the probe electrode. CONSTITUTION:By approaching a distance between the probe electrode 102 and a conductive material to around 1nm as impressing a voltage between them, the position detection is performed on the recording medium 1 having regular atom arrangement or a reference origin formed arbitrarily by using the flow of a tunnel current, and detecting change in a distinctive tunnel current corresponding to the reference scale setting the regular atom arrangement or the reference origin as the reference scale. And based on the result of the position detection, the position control of the probe electrode on a desired recording or reproducing position on the recording medium is performed. In such a way, it is possible to obtain the recording with high density.
