Abstract
According to one embodiment, a magnetic recording medium includes a first layer and a second layer. The first layer includes a first magnetic region, a second magnetic region, and a nonmagnetic region provided between the first and second magnetic regions. A direction from the second magnetic region toward the first magnetic region is along a first direction. The second layer includes third, fourth, and fifth magnetic regions. At least a portion of the fifth magnetic region is provided between the third and fourth magnetic regions. The third magnetic region overlaps the first magnetic region in a second direction crossing the first direction. The fourth magnetic region overlaps the second magnetic region in the second direction. The fifth magnetic region overlaps the nonmagnetic region in the second direction. An easy magnetization axis of each of the first to fifth magnetic regions is aligned with the second direction.
