Abstract: An apparatus capable of detecting a displacement of a probe from a track of a recording medium caused by track fluctuations, vibrations at recording/reproducing period. For example, a probe 1 is maintained to vibrate at frequency f in the direction perpendicular to a data train 4 at an amplitude smaller than the width of the data train 4. In this case, the amplitude of a reproduced signal of the data train changes with the displacement between the probe 1 and the data train. The envelope signal i of the reproduced signal is phase detected using as a reference signal the vibration waveform (standard signal) at frequency f o of the probe 1, to obtain a signal proportional to the displacement from the data train. Using this signal, it becomes possible to feedback control the probe 1 so as to make it trace the data train.

Abstract: A cantilever type probe comprises a cantilever-shaped displacement element having electrodes (5-10) for driving which displace two layers (3,4) of piezoelectric material at the interface and first and second surfaces of the layers, respectively, and each of the electrodes being arranged separately within the same plane, and a tip (1) for information input and output connected to electrodes for drawing out arranged separately from the electrodes for driving at the free end of either one of the first and second surfaces of the element. A scanning tunneling microscopy or an information processing device comprises the cantilever type probe, a driving means for driving the displacement element of the cantilever type probe and a bias or pulse voltage application means for applying a bias or pulse voltage between a sample and the probe.

Abstract: This specification discloses a method of recording information on a recording medium which has the relative scanning of the recording medium by a probe for information recording, the relative scanning being effected along the surface of the recording medium, the recording medium being capable of forming two or more kinds of state changes relative to the state of non-recording, and a recording process onto the recording medium through the probe effecting the relative scanning, the recording process being carried out by intermittently forming bits on the recording medium, each of the bits being formed with one of the two or more kinds of state changes in conformity with recording information. The specification also discloses a method of reproducing information recorded on a recording medium by such information recording method. The specification further discloses an apparatus for carrying out the information recording method, and an apparatus for carrying out the information reproducing method.

Abstract: A probe unit (Fig.1) is provided that is suitable for example for use in a scanning tunnel microscope or the like. The electrical probe contact (7) of this unit is centrally located and mounted upon a flexible member (4,5,6). The flexible member (4,5,6) is symmetrically supported (3) at its periphery and is constrained thus so that the electrical probe contact (7) can only move back and forth in a single direction. Flexure of the flexible member (4,5,6) may be driven by electrostatic or piezoelectric forces. Alternatively, the flexible member may include a layer of piezoelectric material, the elongation or contraction of which will cause flexure.
