Embodiment Construction
[0044] The invention will be described below based on the embodiments shown in the drawings. The present invention is not limited to these examples.
[0045] (first example)
[0046] figure 1 is a schematic sectional view showing a magneto-optical recording medium of a first example of the present invention.
[0047]
[0048] The magneto-optical recording medium of the first example has a soft magnetic film 2, a protective film 3, a resin layer 4, a reflective film 5, a lower dielectric material film 6, a recording film 7, an upper dielectric material film 8 and a cover layer by sequentially forming on a substrate 1. The cumulative structure obtained by layer 9.
[0049] Glass, silicon, or the like having as high rigidity as possible is used as the substrate 1 .
[0050]A material having magnetic properties is used as the soft magnetic film 2 in order to concentrate the magnetic flux, and FeC, FeNi, FeAlSi, CoZrNb, etc. can be used.
[0051] The protective film 3 is mad...
