    摘要： A magnetic recording layer is formed on an auxiliary magnetic layer in a perpendicular magnetic recording medium. The auxiliary magnetic layer has the axis of easy magnetization in the vertical direction perpendicular to the surface of a substrate. The perpendicular magnetic recording medium reliably allows establishment of the magnetization in the auxiliary magnetic layer in the vertical direction. When a magnetic flux flows along the vertical direction perpendicular to the surface of the magnetic recording layer, the magnetic flux flows across the magnetic recording layer in the vertical direction. The magnetization is thus reliably established in the magnetic recording layer in the vertical direction. The magnetic field of a stronger intensity is thus leaked out of the magnetic recording layer in the vertical direction.

    摘要： 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.
