ABSTRACT:
A method of access of a probe electrode to a recording medium having on the surface thereof an edge portion having a level difference larger than a recording recess-projection or having an electron state different from a recording electron state comprises steps of detecting the edge portion; causing the probe electrode to scan at a certain angle to the edge portion; and moving the recording medium to a direction along the edge portion. A method for processing information including recording, reproducing, and erasing of information by access of a probe electrode to a recording medium having on the surface thereof an edge portion having a level difference larger than a recording recess-projection or having an electron state different from a recording electron state comprises steps of detecting the edge portion; causing the probe electrode to scan at a certain angle to the edge portion; and applying a pulse voltage for recording or erasing, or a bias voltage for reproducing information between the recording medium and the probe electrode.
