<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a magnetic recording medium having a magnetically separated magnetic recording pattern, with which the surface of a magnetic layer is not oxidized nor is halogenated, nor is the surface contaminated with dust, nor are the manufacturing steps complicated. Ž<P>SOLUTION: The manufacturing method of a magnetic recording medium has magnetic recording patterns magnetically separated from one another. The method includes steps of: forming a magnetic layer 2 on a nonmagnetic substrate 1, forming a mask layer 3 on the magnetic layer 2 to form magnetic recording patterns, irradiating the areas 7 of the magnetic layer not covered by the mask layer 3 with an ion beam 10 to remove upper layers of the area 7 in the magnetic layer 2 and to modify the magnetic property of a lower layer 8, and removing the mask layer 3, in this order.
