摘要： Stable writing is performed in a super high density hard disk where writing by magnetic field is difficult. A layered thin film structure including at least a magnetic metallic layer/a non-magnetic metallic layer/a magnetic metallic layer is formed, and a metallic probe is brought close to this multilayer film on the order of nano-meters. A quantum well state created in the multilayer film is changed by applying a voltage between the metallic probe and the multilayer film, resulting in a relative magnetic field between the magnetic metallic layers being changed. At this time, an assistance magnetic field is applied in the writing magnetization direction.

摘要： A method for writing information on a highly coercive recording medium stably with an electric field applied through a metal probe and with a magnetic field applied from external and an information recording system that employs the method. The recording medium includes a substrate, a first ferromagnetic layer formed on the substrate, a nonmagnetic layer formed on the first ferromagnetic layer, and a second ferromagnetic layer formed on the nonmagnetic layer. The coercivity Hc2 of the second ferromagnetic layer is larger than that Hc1 of the first ferromagnetic layer. A magnetic field H is applied to the magnetic recording medium from a magnetic pole to change the magnetizing direction of the first ferromagnetic layer to a direction of the applied magnetic field, then a positive or negative voltage V is applied between the metal probe and the magnetic recording medium to change the quantum well level energy between the first and second ferromagnetic layers, thereby inducing an exchange magnetic field HE. As a result, the magnetizing direction of the second ferromagnetic layer is changed with both the exchange magnetic field HE and the magnetic field H.

摘要： An information storage device having a hard disk has a metal probe that is brought closely to the surface of a multilayer film that includes a magnetic metal layer, a non-magnetic metal layer, and a magnetic metal layer up to a nano-meter order distance from the surface. The distance between the metal probe and the surface of the multilayer film, as well as the voltage to be applied are changed to change the state of the quantum well generated in the multilayer film, thereby changing the magnetizing direction relatively between the two magnetic metal layers. To read magnetization information from the hard disk, a change of an optically induced tunnel current is used. The change of the tunnel current is caused by a change of a plasmon resonance energy according to a relative change of the magnetizing direction between the magnetic metal layers.

摘要： An optical signal synthesizer having an optical slab waveguide constructed from three layers in which optical pulses are introduced. A first cut-away portion of the optical slab waveguide has a plano-concave shape serving as a plano-convex lens which collimates the introduced optical pulses, a second cut-away portion of the optical slab waveguide serving as a diffraction grating for parallel light beams in which the optical pulses are separated into every frequency, and a third cut-away portion of the optical slab waveguide has a plano-concave shape serving as a plano-convex lens by which the separated optical pulses are focused on a different spatial position associated with each frequency. A spatial light modulator is fabricated at the focusing position in the optical slab waveguide which allows the optical pulses subjected to optical modulation every frequency to pass therethrough according to an applied electrical signal. A fourth cut-away portion of the optical slab waveguide has a plano-concave shape serving as a plano-convex lens which collimates each modulated optical frequency component individually, and a fifth cut-away portion of the optical slab waveguide serving as a diffraction grating for the modulated optical pulses restores the modulated optical pulses to the parallel light beams.
