Abstract
A magnetic recording apparatus has a magnetic recording media including a substrate and a magnetic layer containing magnetic patterns on the substrate, the magnetic layer including data zones to constitute recoding tracks and servo zones, the magnetic patterns of the servo zones being used as address bits, and a magnetic head configured to read signals from the magnetic recording media while flying over the magnetic recording media, in which, in a case where two magnetic patterns used as address bits on the servo zones corresponding to two adjacent recording tracks are arranged in such a manner that one corner of one magnetic pattern is closest to one corner of the other magnetic pattern, the corners of the two magnetic patterns are substantially separated from each other.
