Abstract:
1. A magnetic recording medium, comprising: a substrate; an under layer formed on the substrate; a recording layer formed both radially and circumferentially continuously of a magnetic material on the under layer, the recording layer having tracks; and a thermal conduction layer formed on the recording layer, the thermal conduction layer including first thin films and second thin films, the first and second thin films each being made of a plurality of materials having different thermal conductivities; wherein the first thin films made of a material highest in thermal conductivity among the plural materials are formed on some portions of the thermal conduction layer, with the some portions being located in association with portions of the tracks included in the recording layer; and the second thin films made of a material relatively lower in thermal conductivity than the first thin films are formed between respective pairs of the first thin films within the thermal conduction layer.
