发明名称 Magnetic recording medium and magnetic recording medium manufacturing method
摘要 The magnetic recording medium of the present invention has a pattern formed using a pattern-forming agent in a laminate of multiple layers including a base material and a magnetic recoding layer, wherein the pattern is recognized on the surface of the laminate opposite to the base material, and the pattern-forming agent is distributed through the thickness of the laminate, wherein a region between the center of the magnetic recording layer and a magnetic recording-reading side of the laminate has an area having a density gradient of the pattern-forming agent which gradually declines in the direction from the center of the magnetic recording layer to the magnetic recording-reading side.
