ABSTRACT:
Provided are a magnetic recording medium and a method of manufacturing the magnetic recording medium. The magnetic recording medium includes a substrate, a soft magnetic underlayer formed on the substrate, a texturing layer formed on the soft magnetic underlayer and including a uniform pattern, and a recording layer including magnetic grains and a non-magnetic boundary region isolating the magnetic grains. The magnetic grains and the non-magnetic boundary region of the recording layer are formed into a regular granular structure by segregation according to the regular pattern of the texturing layer. Therefore, a regular granular structure can be formed in the recording layer without a process such as etching of the recording layer, so that the recording density of the magnetic recording medium can be largely improved.
