Abstract
A magnetic recording medium includes a continuous recording layer, and a seed layer including a surface held in contact with the recording layer. The seed layer includes an oxidized region and a non-oxidized region in the surface held in contact with the recording layer. The recording layer includes a recording magnetic region and a non-recording magnetic region. The recording magnetic region corresponds in position to the non-oxidized region and has perpendicular magnetic anisotropy. The non-recording magnetic region corresponds in position to the oxidized region.
