Magnetic recording medium and production method therefor

Abstract

An object is to provide a magnetic recording medium with a recording region having little magnetic property degradation, and to provide a production method therefor. This method for producing the magnetic recording medium comprises the steps of preparing a structure having a plurality of magnetic material regions 11 with a columnar structure made of a magnetic material separated by non-magnetic material regions 12 made of a non-magnetic material; forming a mask pattern 13 on a portion to be a recording region in the structure; and removing the magnetic material in a plurality of the magnetic material regions 11 in the regions on which the mask pattern 13 is not formed, in the structure, or transforming magnetic properties of the magnetic material, to arrange separation regions which magnetically separate adjacent recording regions.
