摘要：
According to one embodiment, a cured first ultraviolet-curing resin material layer having a first three-dimensional pattern is formed on a first principal surface of a magnetic recording medium having a central hole. A cured second ultraviolet-curing resin material layer having a second three-dimensional pattern is formed on a second principal surface opposite to the first principal surface of the magnetic recording.
