摘要:
On a magnetic recording medium, a servo pattern is formed in a servo pattern region on at least one surface of a substrate by a concave/convex pattern including a convex part, at least protruding end part of which is formed of magnetic material, and a concave part. The servo pattern region includes an address pattern region and a burst pattern region, wherein the convex part is formed in the servo pattern region so that a larger of an inscribed circle with a largest diameter out of inscribed circles on an open surface of the concave part formed in the address pattern region and an inscribed circle with a largest diameter out of inscribed circles on an open surface of the concave part formed in the burst pattern region is an inscribed circle with a largest diameter out of inscribed circles on an open surface of the concave part formed in the servo pattern region.
