A magnetic recording medium is form in sequence with non-magnetic substrates, SiOx (x = 1.2 ~ 1.95), the bottom ferromagnetic metal layer constructed by Co-Ni alloy, the medium layer SiOx (x = 1.2 ~ 1.95), the top ferromagnetic metal protection layer constructed by Co-Ni alloy, and lubrication layer. The measured steam coating angle formed by the normal lines of the top and bottom ferromagnetic metal layers is smaller in which the angle is closer to the surface.
