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. |

DETAILED DESCRIPTION An object of the present invention is to provide a method of access for a recording medium, which is free from the above-mentioned disadvantages, realizes high-density of recording-reproducing by utilizing the characteristics of STM, and enables high-speed access to recorded position with a recording medium of low price and high productivity.
Another object of the present invention is to provide an information-processing apparatus and an information-processing method which enables high-density recording and high-speed reproduction.
According to an aspect of the present invention, there is provided 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: the method comprising 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.
According to another aspect of the present invention, there is provided 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: the method comprising steps of detecting the edge portion; deciding an azimuth angle of a data line to the edge portion; and causing the probe electrode to scan starting from the edge portion to the azimuth of the data line.
According to still another aspect of the present invention, there is provided 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: the method comprising 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
