ABSTRACT:
A magnetic recording medium which is thermally stable and produces low media noise. By providing a plurality of intermediate layers made of a CoCr alloy of which saturation magnetic flux densities are controlled within a predetermined range, the magnetic recording medium simultaneously realizes both a high S/Nm and thermal stability.
