    摘要： Information detecting apparatus comprises a probe arranged to face an information medium so as to relatively move to the information medium with thereby detect information thereon, a first vibrating device for vibrating the probe relative to the information medium in a first direction parallel with the information medium, and a first movement detecting device for detecting a state of relative displacement of the probe for the information medium in the first direction on the basis of information obtained by the probe which is caused to vibrate by the first vibrating device. A second vibrating device vibrates the probe relative to the information medium in a second direction which is parallel with the surface of the information medium and crosses the first direction, and a second movement detecting device detects a state of relative displacement of the probe with the information medium in the second direction on the basis of information obtain by the probe which is caused to vibrate by the second vibrating device.

    摘要： An edge detector is disclosed, which detector is improved by providing a probe moving relatively with a tested pattern, a device for detecting a working force or a tunnel current generated between the probe and the tested pattern, and a device for detecting an edge of the tested pattern according to the detected working force or tunnel current. An edge of the tested pattern is detected at high resolution by detecting the tunnel current flowing between a conductive tested pattern and a probe kept closely opposite thereto, or by detecting an atomic force or a magnetic force working between an insulated or a magnetic tested pattern and a lever.

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