摘要：
To provide patterned media having novel structure. Plural convex members 2991 are provided in an array form on a substrate 2990. The convex member has a shape such that the cross section at each plane in parallel to the substrate tapers toward the substrate. Magnetic recording layers 2992 are provided on upper parts 2993 of the convex members so that they are not in contact with each other between the adjacent upper surface parts.
