摘要:
An accessing method which is a method for accessing a probe electrode to the standard position of the format pattern relative to a medium having a format pattern having a standard position includes the step of scanning the probe electrode so that the probe electrode crosses over the format pattern and detecting the change in tunnel current which occurs by such scanning, and the step of detecting the standard position of the format pattern based on the change in tunnel current detected and moving the probe electrode to the standard position detected. An information processing method containing the step of scanning the probe electrode along the format pattern and reading the information by detection of the tunnel current and an information processing device therefor are also disclosed.

In an information recording medium where information is recorded and/or reproduced by a probe performing relative scanning, an information region for detecting abnormality of the probe is provided separate from a region where information is recorded and/or reproduced. Also disclosed is an information recording and/or reproducing method for recording information on and/or reproducing information from an information recording medium while relatively scanning the recording medium by a probe, which includes a step of detecting abnormality of the probe by detecting a predetermined information region separated from a region where the information is recorded and/or reproduced on the information recording medium. Also disclosed is an information recording and/or reproducing apparatus for recording information on and/or reproducing information from an information recording medium while relatively scanning the information recording medium by a probe, which includes an abnormality detection device for detecting abnormality of the probe according to a result of a detection by the probe of a predetermined information region separated from a region where the information is recorded and/or reproduced on the information recording medium.
摘要:
An apparatus and method for recording and/or reproducing information onto/from a medium through a probe electrode. A voltage is applied between the medium and the probe electrode and a distance between the medium and the probe electrode is adjusted in such a manner that current becomes a predetermined current value, the current flowing to the probe when the voltage is applied between the medium and the probe electrode. The predetermined current value is changed in accordance with the voltage being applied.
摘要:
A probe closely positioned to an information carrier in apparatus to effect information reading and/or input on the information carrier is formed by opposing an electrode to an end portion of the probe to be formed. The distance between probe end portion and the electrode is detected to control the position of the electrode with respect to the probe. A voltage is applied to the probe end portion through the electrode under positioning control to form the probe end portion. The probe end portion is formed and may be reformed to maintain reliable performance of the information reading and/or input apparatus.
摘要:
Information is recorded by providing a recording medium having a recording layer on an electroconductive substrate transmitting an electromagnetic wave and an electroconductive optical probe arranged proximate to the recording medium, and applying a voltage between the substrate and the optical probe. The recorded information is read by irradiating an electromagnetic wave, preferably with a plurality of wavelengths, on the recording layer from the substrate side, and detecting with the optical probe an electromagnetic wave oozed out on the surface of the recording layer.
摘要:
A method and apparatus for detecting the relative positional displacement between a mask and a wafer. The mask is provided with a cantilever. The position mark is provided on the wafer so as to face the cantilever. A relative positional displacement between the mask and the wafer is detected from a deformation amount of the cantilever based on a force acting between the position mark and the cantilever upon relative movement of the position mark and the cantilever.

摘要:
An information detection apparatus is disclosed. A plurality of probes are arranged in the apparatus so as to face a medium which carries an information, Each of the plurality of probes produces a detection signal from the medium. A performance testing device is provided in the apparatus for testing the performance of each of the plurality of probes. A detection device in the apparatus selects the signal from at least one normal probe on the basis of the test result of the testing device and detects the information in accordance with the selected signal. By such the construction in the apparatus, the detection of the information can be continuously effected even if one of the probes is broken.
