Abstract:
1. A magnetic recording medium comprising: a substrate; a plurality of magnetic bodies, provided on the substrate, in each of which information is stored by heating of the magnetic body with use of plasmons converted from near-field light; and a plurality of separators each separating adjacent two of the magnetic bodies from each other in an in-plane direction of the substrate, the separators each including a metallic body and two first dielectric bodies, the metallic body and the two first dielectric bodies being alternately provided in the in-plane direction of the substrate, the two first dielectric bodies each being provided between the metallic body and a magnetic body, both sides of each of the magnetic bodies in the in-plane direction having contact with two first dielectric bodies, respectively, wherein the in-plane direction is a direction that is substantially parallel to a surface on which the magnetic bodies are formed.
