<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a magnetic recording medium by which a bit patterned medium can simply be manufactured with small injection energy. Ž<P>SOLUTION: A laminated body in which a non-magnetic layer 52 is held between a first magnetic layer 51 and a second magnetic layer 53 is formed. Ions are injected into the non-magnetic layer 52 from the surface of the second magnetic layer 53. Consequently, a non-magnetic recording region 27 is formed in an injection region which extends to the injection direction of ions from the surface of the second magnetic layer 53. At the same time, a recording region 26 mutually separated by the non-magnetic region 27 is formed. In such manufacturing method, a target of ions, that is, the non-magnetic layer 52 is arranged, at a point which is close from the surface of the second magnetic layer 53. The injection energy of ions is suppressed to be low. Damages to the surface of the second magnetic layer 53 are suppressed. For example, power consumption of an ion injector is suppressed to be low, based on the suppression of injection energy. Then, a manufacturing cost of the bit patterned medium is suppressed. The bit patterned medium can be readily manufactured. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
