<p>A medium comprises a first layer consisting of perpendicularly magnetizable magnetic film functioning as a recording layer and a second layer consisting of perpendicularly magnetizable magnetic film functioning as a reference layer, wherein the first layer and the second layer are exchange-coupled, and a direction of magnetization of the second layer can be aligned in a predetermined direction without changing a direction of magnetization of the first layer. The medium also comprises a thermal diffusion layer adjacent to the second layer. The thermal diffusion layer allows enlarged margin of laser power. <IMAGE></p> |
