发明名称 MAGNETIC TRANSFER METHOD AND MAGNETIC TRANSFER MASTER CARRIER
摘要 Applying a magnetic field that varies like a single pulse from a start magnetic field to a maximum transfer magnetic field and then to an end magnetic field to a stacked body of a magnetic transfer master carrier and a perpendicular magnetic recording medium such that the time from the start magnetic field to the end magnetic field does not exceed 100 ms. The master carrier has a transfer pattern of multiple fine elements. 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. 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.
