Abstract
A method of producing a magneto-optical recording medium provided with a reproducing layer on a recording film on a substrate, the reproducing film being in-plane magnetized at room temperature and perpendicularly magnetized at an elevated temperature, and the recording film being perpendicularly magnetized at temperatures between room temperature and its Curie temperature. The method includes the steps of forming the reproducing layer on the substrate while applying a magnetic field in a direction parallel to the film surface of the reproducing film which is being formed, and forming the recording film on the reproducing film.
