PROBLEM TO BE SOLVED: To provide an information recording medium capable of reducing the wear of both caused by contact between a surface of the medium and a magnetic head, and the breakage of both caused by fixing. SOLUTION: Each recess 22 of a magnetic layer 14 formed into a predetermined uneven pattern is embedded with a nonmagnetic material on at least one surface side of a base material 11, and a nonmagnetic layer 15 made of a nonmagnetic material is formed in at least a partial area of each upper surface 1a in each projected part 21 of the magnetic layer 14. The nonmagnetic layer 15 is formed so that its part projects more in the same projecting direction as that of the projected part 21 than other parts. COPYRIGHT: (C)2006,JPO&NCIPI
