Abstract: A recording and retrieval device is disclosed. The recording and retrieval device generates an electron beam which selectively exposes portions of a film to thereby record digital data on the film. An input circuit adjusts a characteristic of the electron beam selectively expose portions of the film. An anode target is exposed to the electron beam through exposed portions of the film and arranged to generate anode current indicative of digital data stored on the film. A support may secure a sheet of film such that electrons pass through exposed portions of the film. An output circuit operatively coupled to the anode couples the anode current to an external output device.

Abstract: 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.
