摘要:
An information recording and reproducing apparatus of the present invention, in which a tunnel current is utilized for recording information to a recording surface of a recording medium and/or for reproducing information from the recording surface, includes a slider which is arranged on the recording surface and floats above the recording surface by an air flow caused by movement of the recording medium. The slider includes a body having a first surface positioned opposite to the recording surface, a second surface parallel to the first surface, and a third surface oblique to the first and second surfaces. The slider further includes a cantilever having a projecting portion projecting from the body so as to be substantially parallel to the recording surface and a tip for detecting the tunnel current formed on a surface of the projecting portion on the side of the recording surface.

A sample and the tip portion of an alternating current scanning tunneling microscope are electrically enclosed within a cavity with electrically conductive walls. The dimensions of the cavity are smaller than the wavelength of a component of the AC signal applied by the probe to the sample so that the output signal detected by the probe from the sample will not be contaminated by resonant effects of the cavity.

The electrostatic information recording medium of the present invention has an electric charge retaining layer 11 stacked on at least an electrode layer 13, as shown in FIG. 1 . The electric charge retaining layer is formed from either 1 resin selected from among fluorocarbon resins and polystyrene resins, and an insulating organic substance having no photoconductivity. The electrostatic information recording medium may be produced, as shown in FIG. 5 , by stacking an insulating resin layer 10 on an electrode layer 13, stacking a photoconductive or electrically conductive fine particle layer 11 on the insulating resin layer 10, and further stacking an insulating resin layer 12 on the fine particle layer 11 to a thickness of 0.1 .mu.m to 1 .mu.m. The electrostatic information recording medium is superior in electric charge retaining characteristics, particularly in the performance of retaining positive information electric charge, and also excellent in heat resistance and moisture resistance. If the insulating resin layers 10 and 12 are formed by coating using a fluorocarbon resin solution, the electrostatic information recording medium can be produced with excellent processability.

The invention relates to a read-write optical memory comprising a plurality of juxtaposed memory cells (11), each receiving a respective light beam (3). Each memory cell contains a storage medium (10), which includes a storage element (23) having stable optical states. The storage element (23) is divided into a number of memory points, and the optical state in a given memory point can be both changed and read by means of a light beam (3) directed towards the memory point. The memory can be implemented entirely without any movable mechanical parts and has a very short read-write time and an exceptionally high storage capacity. Parallel writing and reading of multibit words is possible.

By applying a voltage or signal and withdrawing or injecting an electron or electrons to a layer of material, it is possible to write, erase or read data electrochemically. The layer of material has at least one portion that will reversibly change between charge states in response to the applied voltage or signal and the withdrawal or injection of an electron or electrons. Alternatively, the material of the layer may be such that the portion of the layer of material will dissociate into components in response to the applied voltage or signal and injection or withdrawal of an electron or electrons. The stored data may be read using a scanning tunneling microscope by applying a voltage or signal thereto and detecting the current through, voltage across or signal reflected from the layer to detect the different charge states or structures of different portions of the layer. The signal or voltage applied can be a DC or AC signal, a signal pulse or transient or various combinations thereof. By using a material with more than two charge states or with multiple locations each with different charge states and by applying a signal with and detecting at a single or multiple frequencies, it is possible to write, erase or read multiple bits of information simultaneously.

The invention provides an image forming medium and method, and a recording and playback apparatus in which signals can be recorded on the medium sequentially, similar to a magnetic tape or the like, or simultaneously two dimensionally, similar to a photographic film. The recording medium includes a laminate formed on the surface of a semiconductor substrate having a conductive layer on the undersurface thereof. The laminate is formed of an oxide film, a nitrided film, a photoconductive semiconductor layer and a transparent conductive layer. For recording, an optical image is directed onto the transparent conductive layer while applying a predetermined potential between the transparent conductive layer and the conductive layer.
摘要:
A recording medium of electrostatic capacitance type is recorded with an information signal thereon as variation of geometrical shape of the recording surface part of the recording medium. The signal is reproduced from the recording medium by the variation, in response to the variation of geometrical shape, of the electrostatic capacitance between an electrode of a reproducing stylus tracing relatively the recording surface of the medium and the surface part. At least the surface part of the recording medium having the geometric shape variation is formed by a synthetic resin into which an electroconductive material has been admixed. The synthetic resin forms an outer surface cover of the surface part of the medium thereby to prevent exposure of the electroconductive material to the outside.
