Embodiment Construction
[0036] The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. In the drawings, the widths or thicknesses of layers and regions are exaggerated for clarity.
[0037] figure 2 is a cross-sectional view of a patterned magnetic recording medium according to an embodiment of the present invention.
[0038] refer to figure 2 , the patterned magnetic recording medium according to the current embodiment of the present invention includes a plurality of magnetic recording layers 200 arranged on a substrate 20 at intervals. In one embodiment, the magnetic recording layer 200 is arranged at regular intervals. Each of the magnetic recording layers 200 is a multilayer laminate. The multilayer laminate has a sandwich structure in which a soft magnetic layer 6 is interposed between a first ferromagnetic layer 2a and a second ferromagnetic layer 2b. The first nonmagnetic layer 4a may ...
