<p><P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a magnetic recording medium at a high yield while precisely forming a pattern shape of a magnetic layer. <P>SOLUTION: The method for manufacturing a magnetic recording medium forms a magnetic layer 2 on a nonmagnetic substrate 1, and thereafter partially injects ion into the magnetic layer 2 so as to reform the magnetic properties of the ion-injected place 8 of the magnetic layer 2 to form magnetically separated magnetic recording patterns. A reusable mask material 10 is disposed over the magnetic layer 2 with a gap from the magnetic layer 2, the mask material 10 is irradiated with ion from the top thereof. Through the concaves 10a of a concave/convex pattern corresponding to the magnetic patterns MP formed on the surface of the mask material 10, the ion is partially injected to the magnetic layer 2 located below. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
