Abstract:
According to one embodiment, in a magnetic disk, a reflecting layer with a higher reflectance to near-field light than a magnetic recording layer is provided in the magnetic recording layer so as to be flat. A magnetic head performs magnetic recording on the magnetic recording layer while locally heating the magnetic recording layer based on the near-field light.
