摘要： PURPOSE: A magnetic recording medium and a manufacturing method thereof, and a magnetic recording apparatus are provided to keep exchange coupling energy of the recording layer high even when the exchange coupling strength control layer is formed thick. CONSTITUTION: A magnetic recording medium comprises a first recording layer, an exchange coupling strength control layer, and a second recording layer successively laminated. The first recording layer is composed of a soft magnetic support layer, an intermediate layer, and a perpendicular magnetic anisotropic layer on the substrate. The exchange coupling strength control layer is made including ruthenium. The second recording layer has perpendicular magnetic anisotropy.

摘要： PURPOSE: A magnetic recording medium and a magnetic recording apparatus are provided to keep the exchange coupling energy of the recording layer high even when the exchange coupling strength control layer is formed thick, thereby improving perpendicular magnetic recording characteristic. CONSTITUTION: A magnetic recording medium comprises a substrate, a soft magnetic support layer, an intermediate layer, a first recording layer, an exchange coupling strength control layer, and a second recording layer successively laminated. The first recording layer has perpendicular magnetic anisotropy. The exchange coupling strength control layer is made of a granular material obtained by adding an oxide to metal including ruthenium(Ru). The second recording layer has perpendicular magnetic anisotropy and is ferromagnetically coupled with the first recording layer through the exchange coupling strength control layer.

摘要： A magnetic recording medium and a magnetic recording device are provided to improve record/reproduction resolution of the medium by locating the second magnetic recording layer of granular material on the exchange coupling strength control layer. A magnetic recording medium comprises, as a part of layers laminated on a substrate(10a), a first magnetic recording layer, an exchange coupling strength control layer(10e), a second magnetic recording layer, and a third magnetic recording layer. The first and the second magnetic recording layer are made of granular material. The third magnetic recording layer is made of non-granular material. The first magnetic recording layer has a higher anisotropic magnetic field than the second magnetic recording layer.
