ABSTRACT:
A magnetic recording medium which allows high density recording and has excellent durability can be obtained. A magnetic recording medium includes: a plurality of ferromagnetic material dots arranged on a soft magnetic layer formed on a non-magnetic substrate so as to be separated from one another; and carbon films which are formed on the respective ferromagnetic material dots, each carbon film having a smooth film face shape in a section passing through the center of each ferromagnetic material dot and a film thickness gradually decreasing from the center of the ferromagnetic material dot toward an outer edge thereof.
