An information recording and/or reproducing apparatus includes a recording medium having a plurality of segmented planar electrodes, a plurality of probe electrodes respectively facing and electrically connected to the plural planar electrodes, and a circuit for independently applying a voltage for recording and/or reproducing between each pair of the planar electrodes and the probe electrodes. The information recording and/or reproducing apparatus includes a circuit for inputting information to be recorded on the recording medium. A memory other than the recording medium is used for temporarily storing the input information, and a control circuit applies the recording voltages between the plurality of probe electrodes and the segmented planar electrodes in correspondence with the information stored in the memory.
摘要:
A microtip has a tip portion formed by gathering of three crystal faces of a single crystal, at least one of the crystal faces being an etched face at and around the tip portion. The microtip is produced by breaking and splitting a single crystal by applying a stress, and subjecting the face formed by breaking of the single crystal to anisotropic etching by utilizing facial orientation, thus forming a tip portion as a gathering point of three crystal faces of the single crystal. A surface-observing apparatus for observing a surface of a specimen and an information-treating apparatus comprise a tip in proximity to the specimen to be observed or a recording medium, and conduct the surface observation or the writing or reading by using the tip, respectively.
