ABSTRACT:
An information processor for performing at least one of recording information at a high density, reproducing and erasing information by applying the principle of a scanning tunnel microscope (STM) or an atomic force microscope (AFM) and an information processing method using the information processor. The information .processor is used with a recording medium comprising a recording layer having a characteristic of one of an insulator and a semiconductor. The processor includes a substrate electrode in the recording medium, at least one probe electrode disposed close to the recording medium, and at least one of a circuit for applying an information recording pulse voltage and a circuit for applying an information reproducing pulse voltage. A maximum difference in surface level of a 1.times.1 .mu.m surface region of the substrate electrode is 1 nm or less, and the radius of curvature of a tip of the probe electrode is in the range of 0.1 to 200 .mu.m. The processor further includes a device for controlling the distance between a surface of the recording medium and the tip of the probe electrode.
