To improve the sliding characteristics of a magnetic head by reducing a friction coefficient, and realize a magnetic recording medium with a high recording density and a large capacity, capable of reducing the flotation distance of the magnetic head. On the surface of a base, aluminum containing nitrogen aggregates locally to form islands of metal deposits, which are distributed discretely over the entire surface of the base. Meanwhile, on the metal deposits, a metal base layer, a magnetic layer, a protective layer, and a lubrication layer are laminated sequentially to form a magnetic recording disk. On the disk surface, ultrafine irregularities are formed that reflect the shapes of the metal deposits, thereby realizing a reduction in the friction coefficient. |
