摘要:
A method for positioning an information processing head at a predetermined position on a recording medium includes detecting a predetermined magnetization pattern on a magnetic material having a predetermined positional relation to a recording region of the recording medium by a magnetization detector having a predetermined positional relation to the information processing head, generating a signal indicative of a relative position of the information processing head with respect to the recording medium based on a result of the detecting step and moving the information processing head and the recording medium relatively to position the information processing head at the predetermined position with respect to the recording medium based on the generated signal, and a process for forming a cantilever-type probe capable of indicating a magnitude of a magnetic force between the probe and a recording medium and capable of performing at least one of a recording operation and a reproducing operation on the recording medium.
摘要:
A recording medium includes a substrate electrode, a recording layer constituted of a monomolecular film of an organic compound or a built-up film thereof, and a photoconductive thin film, laminated in this order on a substrate. The photoconductive thin film may preferably be divided to a plurality of isolated sectors. The recording medium is used in an ultra high density information processing apparatus with a probe electrode disposed close to the medium, a power source for applying a voltage between the medium and the probe electrode, and a light source for irradiating the medium.
摘要:
An electrode substrate and a recording medium having a smooth surface with surface unevenness of 1 nm or less and a size of 1 &mgr;m□ or more are disclosed. An electrode substrate and a recording medium having a concave-shaped groove for tracking on the surface, which groove has a depth which can detect of the tunnel current from the bottom thereof by a probe electrode for scanning the surface are also disclosed. Information processing devices equipped with the smooth recording medium, an electroconductive probe arranged approximate to the recording medium and a pulse voltage application circuit for recording are also disclosed.
摘要:
A method for detecting a slope of a surface of an information record medium in an apparatus for detecting/writing information using one or a plurality of probes from/in the information record medium. The surface of the information record medium is scanned using the probe. The information from the surface of the information record medium is detected through the probe when the scanning is executed, and the slope of the surface of the information record medium is detected on the basis of the detected information.
摘要:
An information carrier for performing information recording and/or reproducing through a probe provided in an information recording and/or reproducing apparatus includes an information recording medium having a recording plane for recording and/or reproducing through the probe, and a frame which is formed detachably in the information recording and/or reproducing apparatus to accommodate the information recording medium airtightly. A mechanism is provided in the frame which can be opened or closed to allow the recording plane of the information recording medium to be open when the frame is mounted in the information recording and/or reproducing apparatus. The recording plane of the information recording medium is allowed to face the probe through the opening caused by the mechanism, and this mechanism performs the opening in a closed space formed by the cooperation of the frame and the information recording and/or reproducing apparatus when the frame is mounted in the information recording and/or reproducing apparatus, thereby preventing the property degradation of the recording medium and the probe electrode as well as damage and adhesion of dust particles.

摘要:
A method of driving a device having a pair of electrodes and organic insulating layer sandwiched therebetween. The device exhibits at least three states of different electroconductivities in response to an applied voltage. A transition from the first state to the second state is achieved by applying a voltage within a first predetermined range to the device in the first state, and a transition from the second state to the third state is achieved by applying a voltage within a second predetermined range to the device in the second state.
摘要:
Recording, reproduction or erasing of information is performed on a recording medium having a recording layer provided on an electrode substrate. The electrode substrate has a regular periodic structure within a plane and the structure is detected through the recording layer by use of a probe electrode to determine a desired position on the recording medium.
