Abstract

Recording, reproduction or erasing of information is performed on a recording medium having a recording layer provided on an electrode substrate. The electrode substrate has a regular periodic structure within a plane and the structure is detected through the recording layer by use of a probe electrode to determine a desired position on the recording medium.
