Abstract: Information is recorded by preparing a recording medium having a recording layer on an electroconductive substrate transmitting 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 electromagnetic wave, preferably with a plurality of wavelengths, on the recording layer from the substrate side, and detecting electromagnetic wave oozed out on the surface of the recording layer by the optical probe.

Abstract: Information recording/reproducing apparatus and method by use of probe electrodes are disclosed. In this method, information to be recorded on a recording medium is encoded. The encoded information is distributed to a plurality of probe electrodes. The plurality of probe electrodes are driven on the basis of the distributed information so as to record the information on the recording medium. In reproduction, the information recorded on the recording medium is read out from the recording medium by use of the plurality of probe electrodes. The information read out from the recording medium is stored by use of the plurality of probe electrodes. The stored information is decoded to reproduce the information recorded on the recording medium. The encoding is performed by changing the information to be recorded to information added with an error correction code.

Abstract: An image signal processing apparatus for temporarily storing image information, and outputting the information after signal processing is disclosed. The apparatus includes a dividing unit for dividing the input image information, a memory which stores the divided information, and a control unit for controlling a scanning unit of the memory so as to edit and output the image information. The memory includes a plurality of probe electrodes, a recording medium arranged to oppose the probe electrodes, the scanning unit for moving the probe electrodes relative to the recording medium so that the probe electrodes scan the surface of the recording medium, and a voltage application unit for applying a voltage between the recording medium and each probe electrode so as to record the divided information in each scanning region on the recording medium of the probes, and to reproduce the divided image information recorded in each scanning region.

Abstract: 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.

Abstract: A method and apparatus for driving an electron source in which a high-quality image display is presented by correcting a non-uniform effective current distribution caused in cold cathode elements by leakage current. A digital video signal enters a shift register where a serial-to-parallel conversion is made for each line of an image based upon a shift clock signal. One line of the image data that has been subjected to the serial-to-parallel conversion is latched in a latch circuit and then applied to a voltage modulating circuit. The latter voltage-modulates the input data and sends the modulated signal to a voltage/current converting circuit. The latter converts the voltage quantity to a current quantity, which is applied to each of the cold cathode elements of a display panel through respective column terminals. A voltage V1 is applied to the selected row wire, and a voltage V2 (V2 NOTEQUAL V1) is applied to all other row wires, for controllig the leakage current.

Abstract: This specification discloses an apparatus for and a method of moving a probe for causing a physical phenomenon to occur between it and a predetermined object and the object relative to each other to make the probe approach the object. At least one of the probe and the object is driven in a predetermined direction to displace one of the probe and the object in the predetermined direction relative to the other. A physical phenomenon occurring between the probe and the object is detected. At least one of the probe and the object is driven so as to bring the probe and the object close to each other. The driving for the approach of the probe to the object is controlled on the basis of the result of the detection of the physical phenomenon during the driving in the predetermined direction. The specification also discloses an information detection and/or input apparatus using such apparatus and method.
