Magneto-optical recording medium

A magneto-optical recording medium comprising:

• a heat-radiation film;
• and
• a magnetic film exhibiting magnetic anisotropy in a direction vertical to a surface of the magnetic film,
• wherein the heat-radiation film is formed between a substrate and the magnetic film and is formed of a plurality of alloy films having different thermal conductivities, and of the alloy films, the nearest one to the substrate has the highest thermal conductivity and the farthest one from the substrate has the least rough surface.

A process for forming a magneto-optical recording medium including a first dielectric film, a first heat-radiation film, a second heat-radiation film, a second dielectric film, a magnetic film and a third dielectric film formed on a substrate in this order, the process comprising the steps of:

• forming, as the first heat-radiation film, an alloy film having a higher thermal conductivity and a larger thickness than the second heat-radiation film;
• etching a surface of the first heat-radiation film to flatten the surface;
• and
• forming the second heat-radiation film on the flattened surface of the first-radiation film.
