Magnetic transfer method and magnetic transfer master carrier

A magnetic transfer method for transferring a transfer pattern, which is designed for transferring desired information to a perpendicular magnetic recording medium for use in a recording/reproducing device having a rotary read/write head for scanning a disk in an arc shape intersecting concentric tracks, provided on a surface of a magnetic transfer master carrier to a perpendicular magnetic recording medium by applying a magnetic field to a stacked body of the magnetic transfer master carrier and the perpendicular magnetic recording medium tightly stacked on top of each other such that a central portion of the transfer pattern is aligned with a central portion of the perpendicular magnetic recording medium, wherein:

• the transfer pattern is constituted by multiple fine elements and each element has a planar shape formed of a plurality of rectangles, each having two sides parallel to a circumferential tangent line and two sides forming an angle of 90±5° with the circumferential tangent line, arranged continuously in a track width direction in each concentrically provided track, and a side of the planar shape of each element intersecting the circumferential tangent line has an effective inclination corresponding to a skew angle of the read/write head in each track;
• and
• the magnetic field is a circumferential magnetic field concentric to the stacked body, varied in strength like a single pulse from a start magnetic field smaller than a magnetization reversal magnetic field of the perpendicular magnetic recording medium to a maximum transfer magnetic field and then to an end magnetic field smaller than the magnetization reversal magnetic field, and applied to the stacked body such that the time from the start magnetic field to the end magnetic field does not exceed 100 ms.
