摘要:
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.

摘要:
A recording-reproducing apparatus, comprising a material (1), in which an intramolecular electron distribution can be changed, by electromagnetic wave irradiation and electric field application, a probe electrode (2) brought close to the material, a means (15) for projecting an electromagnetic wave onto the material, and a means (8) for applying an electric field between the material and the probe electrode, is provided.
摘要:
Disclosed is an optical information recording/reproducing system comprising: a recording medium composed of a recording- bit producing layer, which is formed of a fluorescent substance (2), and a photoconductive layer (3), both interposed between conductive layers (4, 1) at least one of which is transparent; means for selectively applying a voltage to both sides of the recording medium; means for radiating an optical recording beam to a site to be recorded on the recording medium while applying a voltage to the recording medium and then, applying a high electric field to the recording-bit producing layer by way of the photoconductive layer the resistence of which has been lowered at the site, whereby developing a dielectric breakdown and hence causing the fluorescent substance to lose the fluorescence thereof so that information is recorded; and means for radiating an optical reproducing beam on the recording medium without applying any voltage to the recording medium and then, reproducing information depending on whether fluorescence has been produced.
摘要:
This invention concerns data storage memory, writable and readable using at least one writing (60) or reading micropoint which touches on a contact point with a dedicated writing or reading point on the surface of a substrate, either to modify the physical state of the zone, in reading or erasure mode, or to determine the physical state of the zone since the data stored in the zone is defined by the physical state of the zone. The surface of the substrate is subdivided into aggregated individual *batches (75) composed of one layer of a first sensitive material whose state can be modified by the application of a writing micropoint, each *batch (75) being surrounded by a box (80) made of a second material with little or no sensitivity to the application of the writing micropoint, with this second material completely separating the individual *batches from each other. The material of the boxes is the same as that of the *batches although they are differentiated by differentiating impurities. The organization into *batches and into boxes may be achieved using photolithography or through a process of self-organization of materials that can be spontaneously agglomerated into *batches.
摘要:
An electrical read head having high sensitivity and resolution power and a method of operating the same are provided. The electrical read head includes a core portion (44) for recording/reading data on/from a recording medium and an electrode pad (60,62) connecting the core portion (44) to a power supply. A surface of the core portion (44) facing the recording medium is a plane surface and side surfaces of the core portion are perpendicular to the plane surface.
摘要:
A memory device, including a plurality of nanoscale memory cells (1510, 1512) created by applying pressure to and removing pressure from one or more regions (1510, 1512) of a substance (1502) to change the electrical conductivity of those regions (1510, 1512). An electrically conductive read probe (1514) determines the conductivities of the regions and thereby the information stored in the cells. A write probe (1508) applies pressure to and removes pressure from selected cells to change the electrical conductivity of those cells and thereby store or erase information.
