As a result of the numerous investigations it was found that the thermo magnetic method is most comfortable and cheap. The magnetic film is placed to the radiation area. The recording magnetic field is applied in the films plane. The influence of radiation occurs at the several parts of the magnetic film. It was found that at 973°K the perpendicular magnetic anisotropy have arise in the polycrystalline films, the films be come homogeneously magnetized. The films with the thickness of 100-150°A were obtained by the thermal evaporation of the alloys.
