A magnetic recording medium includes a first upper layer, a first lower layer below the first upper layer, an intermediate layer, provided between the first upper layer and the first lower layer, which magnetically couples the first upper layer and the first lower layer. The first lower layer includes a second upper layer, a second intermediate layer below the second upper layer, and a second lower layer below the second intermediate layer. Coercive force of the first upper layer is higher than coercive force of each of the second upper layer and the second lower layer. The second upper layer and the second lower layer are antiferromagnetically coupled via the second intermediate layer.
