Abstract: A cantilever unit comprises a cantilever for supporting a probe and a displacement amount detecting means, the displacement amount detecting means being integrated with the cantilever. An information processing apparatus comprises the cantilever unit and optionally an information recording medium stationed in close vicinity to the unit, wherein an information in the medium is reproduced at a signal on the basis of a displacement amount of the cantilever. An atomic force microscope and magnetic force microscope comprise the cantilever unit, respectively.

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 recessprojection 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.

Abstract: A matrix comprising blocks, each made up of a set of thin-film unit elements of semiconductor, either light-sensitive or controlling a light valve, is driven by applying voltage pulses (T1, T2 etc) to the blocks in turn, and while each block is enabled, selected elements in that block are read or energized. To reduce dark current, a short pulse P is applied to all of the blocks in the gaps between the enabling pulses. The number of pulses P applied to each block before enablement may be finite, eg 5 to 10, and yet provide adequate reduction in dark current.

Abstract: An image information processing apparatus for processing image information includes a total curvature calculating unit, mean curvature calculating unit, a logical product computing unit and a median filter. A total curvature at each pixel of the image information is calculated by the total curvature calculating unit. A mean curvature at each pixel of the image information is calculated by the mean curvature calculating unit. The logical product computing unit executes computation of a logical product of outputs from the total curvature calculating unit and the mean curvature calculating unit. An output from the logical product computing unit is filtered by the median filter.

Abstract: An information processing apparatus for effecting recording of information on and/or reproduction of information from a recording medium is provided with a probe electrode, a cantilever piezo-electric member, a controller and a detector. The probe electrode is relatively displaced to the recording medium by the cantilever piezo-electric member. The controller applies a control signal to the cantilever piezo-electric member to control the cantilever piezo-electric member. The detector detects a minute signal obtained on the tunnel effect caused between the probe electrode and the recording medium. A switch element is further provided on the apparatus so as to electrically disconnect between the cantilever piezo-electric member and the controller during the minute signal being detected by the detector.

Abstract: In an information processing apparatus, at least one of recording and reproduction of information is performed while two-dimensionally scanning a recording medium with a probe, utilizing a physical phenomenon occurring between the probe and the medium. The apparatus includes a scanning mechanism for effecting relative movement between the probe (1) and the medium (3) so as to translate the probe (1) as drawing a circular or elliptic locus on the medium (3) and a recording and/or reproducing circuit for performing at least one of the recording and reproduction of information, utilizing the physical phenomenon during the relative movement.
