摘要： A recording device is disclosed. The recording device generates an electron beam which selectively exposes portions of an electron-sensitive and/or UV light-sensitive film to thereby record digital data on the film. A retrieval device is also disclosed. The retrieval device selectively directs a generated electron beam towards a predefined point on a target. The target is simultaneously exposed to a light pattern formed by shining UV light through exposed portions of an electron-sensitive and/or UV light-sensitive film to thereby develop an output signal representative of digital data stored on the film at a location corresponding to the predefined point on the target.

摘要： A data storage device including a substrate, a data storage layer on the substrate, and a spin-polarized electron source. The data storage layer comprises a fixed number of atomic layers of a magnetic material which provide the data storage layer with a magnetic anisotropy perpendicular to a surface of the data storage layer. A data magnetic field is created in the data storage layer. The data magnetic field is polarized either in a first direction corresponding to a first data value or in a second direction corresponding to a second data value. Data is stored in the data storage layer by providing a spin-polarized electron having an electron magnetic field with a direction of polarization corresponding to one of the first and the second data values, the electron having a wavelength "characteristic" of unpaired electrons in the data storage layer which cause the magnetic moment of the material, and directing the spin-polarized electron at the data magnetic field to impart the direction of polarization of the electron magnetic field to the data magnetic field. Data is read from the data storage layer by directing the spin-polarized electron at a second wavelength at the data magnetic field and detecting a deflection or attraction of the spin-polarized electron by the data magnetic field. Alternatively, data is read from the data storage layer by directing the spin-polarized electron at the data magnetic field so that the magnetic medium produces a secondary electron and then detecting certain characteristics of the secondary electron.

摘要： A method for read/write data onto a recording medium by using a nano-tip array and a data storage device incorporating the nano-tip array. The nano-tip array is fabricated on a silicon on insulator wafer to form a multiplicity of silicon micro-tips first by a MEMS technique, followed by forming integrally on each one of the multiplicity of silicon micro-tips at least one carbon nanotube extending outwardly away from the one micro-tip. The data storage device further includes an anode with a multiplicity of apertures therein with each apertures corresponding to one of the multiplicity of silicon micro-tips, and a recording medium that has an active surface positioned immediately adjacent to the multiplicity of silicon micro-tips.

摘要： A method and apparatus for nondestructive readout of magnetic images stored on magnetic thin films and for recording magnetic inputs on thin films. A uniaxially anisotropic thin film of magnetic material carrying a recorded magnetic image is transported over a transmission line in the presence of a magnetic tickling field. A radiofrequency oscillator is coupled to the transmission line and the tickling field is made to oscillate at a relatively low frequency. The magnetic image recorded on the passing thin film is then read out by detecting the modulation of the radiofrequency signal caused by ferromagnetic resonance absorption. The same apparatus is used for recording by replacing the radiofrequency oscillator with a direct current source and by modulating the tickling field with the signal to be recorded.

摘要： A data storage system is described which includes a magnetostrictive, anisotropic, ferromagnetic film whose domains exhibit a preferred orientation and are initially poled in one direction along the preferred orientation. A field is applied in opposition to the one direction, the field being insufficient to cause a switching of the poled domains. An electrostrictive film is placed in contact with the ferromagnetic film and a writing system is provided to actuate the electrostrictive film to impart stresses to the ferromagnetic film at selected locations. The induced stresses reduce the anisotropy energy of the ferromagnetic film at the selected locations and enable the domains thereat to become poled in accordance with the applied field. In one version of the invention, the writing means comprises a directed energy beam such as a laser or electron beam. In another version, the writing system employs surface acoustic waves in combination with a scanned energy beam.

摘要： By recording, reproducing and erasing information by using a recording thin film of the present invention, the information can be recorded, reproduced and erased by a single beam spot and new information can be rapidly rewritten while recorded information is erased. The irradiation beam is not limited to a light beam but it may be other energy beam such as electron beam or ion beam. The record medium is not limited to a disk but it may be tape or card and is applicable to a recording thin film other than the described thin film and to other methods.By using the described recording thin film, a manufacturing process is simple and reproducible, the recording/reproducing characteristic is high and the information can be stably stored for an extended time period. The record also may be rewritten a number of times.
