    Abstract: A thermal-assisted magnetic storage device includes a magnetic recording media of a transparent material, a first marker of a material that is optically singular compared with materials therearound, and a magnetic head disposed on a magnetic head slider facing a recording surface of the magnetic recording media. A light-beam pickup faces the other surface of the magnetic recording media, so as to emit light therefrom to the surface of the magnetic recording media. A second marker is disposed on the magnetic head slider for roughly guiding the light to the first marker. An alignment between the light and the magnetic head is performed in accordance with the light reflected from the first marker.

    Abstract: A perpendicular magnetic recording medium includes a magnetic orientation controller layer serving as a layer for controlling crystalline orientation in an upper layer. A non-magnetic orientation controller layer extends on the surface of the magnetic orientation controller layer The non-magnetic orientation controller layer serves as a layer for controlling crystalline orientation in an upper layer. A magnetic recording layer extends on the surface of the non-magnetic orientation controller layer. The perpendicular magnetic recording medium allows a reliable establishment of a uniform crystalline orientation in the magnetic recording layer based on the influences from the magnetic and non-magnetic orientation controller layers. A reliable establishment of a uniform crystalline orientation can be achieved without an increase in the thickness of the non-magnetic orientation controller layer.

    Abstract: An ion implanting apparatus is provided, which can accurately measure a quantity of atoms that are implanted. The ion implanting apparatus according to the present invention has an object to be measured, and the object to be measured is arranged in an irradiating range in which ions are irradiated. When atoms are implanted into an object to be processed by irradiating ions of a processing gas and neutralized particles thereof, the object to be measured is heated through the irradiation with the processing gas ions and the neutralized particles. A control unit determines a quantity of the atoms that are implanted into the object to be processed from the temperature of the object to be measured.

    Abstract: A magnetic recording medium suppresses effectively side erasure even when recording dot intervals are reduced. Magnetic dots and a soft magnetic layer are provided on a soft magnetic underlayer with a nonmagnetic layer intervening, so that magnetic dots are separated by the soft magnetic layer, and consequently leakage flux during recording to magnetic dots is absorbed by the soft magnetic layer, side erasure can be suppressed, and moreover the soft magnetic underlayer and soft magnetic layer are separated, so that an influence on recording/reproduction characteristics can be prevented.

    Abstract: The present invention provides a perpendicular magnetic recording medium that reduces medium noise and achieves thermal stability of recording magnetization. This perpendicular magnetic recording medium has a substrate and a recording layer formed by single-layered magnetic nanoparticles that are aligned at uniform intervals. An auxiliary magnetic film that is thinner than the recording layer is interposed between the substrate and the recording layer. The magnetization of the magnetic nanoparticles is secured by the exchange interaction effect of the auxiliary magnetic film.
