Patent attributes
A data track area and a servo pattern area are formed on a magnetic recording medium by embedding a nonmagnetic material inside concaves in a plurality of types of convex/concave patterns formed of a magnetic material on a substrate. The servo pattern area includes a plurality of types of first functional areas, in which control signals for disk access are recorded during manufacturing using the convex/concave patterns, and a second functional area, in which a convex/concave pattern of a different type to the convex/concave patterns of the respective first functional areas is formed and in which the nonmagnetic material is embedded so that an average height within the second functional area is substantially equal to an average height in the data track area.
