Abstract: In an apparatus including a recording medium on which a multiplicity of information bit lines are formed and a probe facing the recording medium, the displacement between the center of the information bit line and the locus of the probe is detected at the time or relatively moving the probe along the information bit line. Tracking is performed in such a manner that the probe scans the center of the information bit line in accordance with the detection results.

Abstract: A recording medium comprises a substrate electrode, a recording layer constituted of a monomolecular film of an organic compound or a built-up film thereof, and a photoconductive thin film, laminated in this order on a substrate. The photoconductive thin film may preferably be divided to a plurality of isolated sectors. The recording medium is used in an ultra high density information processing apparatus with a probe electrode disposed close to the medium, a power source for applying a voltage between the medium and the probe electrode, and a light source for irradiating the medium.

Abstract: A scanning type probe microscope apparatus for measuring a surface state of a sample by scanning the sample by use of a probe is disclosed. In the apparatus, the sample is inclined relative to a scan direction of the probe by a inclination mechanism. Of a signal component corresponding to the surface state of the sample, a signal component having an optional space frequency is selected to be detected by a detecting circuit. The inclination mechanism is controlled on the basis of a detection result of the detecting circuit.
