<p><P>PROBLEM TO BE SOLVED: To provide a recording medium which can effectively suppress noise by a magnetic domain generated in a soft layer in a discrete vertical magnetic recording medium having a soft layer. <P>SOLUTION: The recording medium has a first upper layer 4, a first lower layer 2, and a first intermediate layer 3 which antiferromagnetically combines both layers, and the first lower layer has a second upper layer 2-3 and a second lower layer 2-1 which are lower than the first upper layer in coercive force; and an intermediate layer 2-2 which antiferromagnetically combines both layers. The first upper layer 4 is removed in an area between a first track area in which information is recorded, and a second track area adjacent to the first track area. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
