Abstract: The present invention provides: a method of producing, at low temperature, a magnetic recording medium comprising an L10FePt thin film which is highly (001)-oriented and highly L10-ordered; and a magnetic recording medium comprising an L10FePt thin film that can be obtained by this method. In the production method of a magnetic recording medium (10), a thin film formation step S1 of forming a thin film 2 containing an FePt alloy and an oxide of metal having a melting point of 100° C. or more and 500° C. or less is carried out; an annealing step S2 of annealing the thin film 2 to a predetermined temperature is carried out; thereby a magnetic recording layer 2′ containing the FePt alloy having a L10-ordered structure and the oxide of metal is formed. The magnetic recording medium can be obtained by this production method.
