摘要:
An information recording/reproducing method and apparatus is for carrying out at least one of recording and reproducing information through a probe electrode or through a plurality of probe electrodes on an information recording medium. A probe electrode is disposed on an elastic member. A relative position is so adjusted between the recording medium and the probe electrode that a repulsive force between them is comparative to an elastic force of the elastic member. In case of plural probe electrodes, they are displaced to keep an equal spacing between the recording medium and the respective probe electrodes so that they may have either a zero average or a minimized square sum of displacement. A spacer layer will do for setting a spacing between a probe electrode and the recording medium.

An information processor comprises a plurality of probes disposed so as to face to a recording medium containing an information, and a plurality of elastic members such as cantilevers supporting the respective probes. The processor reads the information by detecting each displacement of the elastic members. For the detection of displacement, the processor has an optical system for radiating a scanning light beam to the elastic members together with an optical system for detecting a reflected light from the elastic members, or alternatively has a means for detecting each displacement individually such as optically integrated optical members or piezoelectric layers provided to the elastic members.
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.

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.
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.

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.

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.
