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.

A probe for reading an information from an object and/or inputting an information to an object is disclosed. The probe has a supporting member and a rod-shaped projection of which the end is positioned opposed to the object for information reading therefrom and/or information input thereto. The rod-shaped projection protrudes from a partial area of the supporting member. The information reading from the object and/or information input to the object is effected at the longitudinal end of the probe. The probe provides precise and accurate output and/or input of information regardless of the surface state of the object.

An electron source emits electrons as a function of input signals. The electron source includes a substrate, a matrix of wires having m row wires and n column wires laid on the substrate with an insulator layer interposed therebetween, and a plurality of surface-conduction electron-emitting devices each having a pair of electrodes and a thin film including an electron emitting region and arranged between the electrodes. The electron-emitting devices are so arranged as to form a matrix with the electrodes connected to the respective row and column wires. The electron source further includes a selector for selecting a row of the plurality of surface-conduction electron-emitting devices, and a modulator for generating modulation signals according to input signals and applying them to the surface-conduction electron-emitting devices selected by the selector.
摘要:
In an apparatus including a recording medium on which a multiplicity of information bit lines are formed and a probe facing the recording medium, the displacement between the center of the information bit line and the locus of the probe is detected at the time of relatively moving the probe along the information bit line. Tracking is performed in such a manner that the probe scans the center of the information bit line in accordance with the detection results.

摘要:
In an information processing apparatus which records and reproduces information by rotating a cylindrical recording medium on the basis of the principles of a scanning type tunnel microscope, the speed of the probe relative to that of the recording medium becomes fixed, and resonance and a decrease in an S/N ratio of reproduced signals during high-speed scanning can be prevented. Thus, information processing at a large capacity and high-speed response with a high degree of accuracy is made possible. An information processing system that records and reproduces information on the basis of the principles of a scanning type tunneling or an atomic force microscope employs a ferroelectric layer in the recording medium to simplify and improve reproduction. The recording medium may include a rotating cylindrical medium wherein the speed of the probe is fixed relative to that of the cylindrical medium to prevent resonance and to decrease the signal-to-noise ratio of reproduced signals during high speed scanning. Large capacity, accurate and high speed information processing is thereby obtained.
摘要:
An apparatus for producing monomolecular films or monomolecular built-up films includes: a trough for accommodating a liquid over the surface of which a monomolecular film is to be spread; a barrier band for defining a region in the trough over which the monomolecular film is allowed to be spread; and a plurality of supports for holding the barrier band within the trough, the supports being arranged at positions where they do not interfere with the surface of the liquid, wherein the loss of the monomolecular film material can be substantially reduced. Further, no local collapse of the molecular film occurs in the vicinity of the supports, thereby making it possible to always provide a uniform LB film.
