Abstract:
A magnetic recording medium comprising a substrate, an underlayer provided on the substrate, and a recording film provided on the underlayer which recording film is formed of at least one magnetic layer, said at least one magnetic layer being made of an alloy containing cobalt as the main constituent thereof, chromium and germanium as additives of the alloy, and containing phosphorous as a third additive of the alloy,wherein a value of BrÃ—t, in which said â€œBrâ€  is residual magnetic flux density of said recording film when measured while applying a magnetic field in a relative traveling direction of a magnetic head during recording to the recording medium and in which said â€œtâ€  is a thickness of the recording film, is not less than 1.6 mA but not more than 5 mA.
