Magnetic transfer method and magnetic transfer device

In a magnetic transfer master carrier (3), as a substrate (3a), one having a Young's modulus E (GPa) in the range of 85 to 250 is used. Magnetic transfer is performed under conditions in which 2‰ ±Ed 3 /{P(S2/S1)}‰ 400 (where the constant ±=7.37×10 9 ) is satisfied, where d (m) is the thickness of the substrate from the bottom face of a recessed portion to the back face, S1 (m 2 ) is the total area of the cross sections of the projected portions which are parallel to the plane of the substrate at a height of 50% of Dmax from the bottom face of the recessed portion when the height from the bottom face of the recessed portion to the top face of a projected portion is denoted by Dmax, S2 (m 2 ) is the total area of the bottom faces of the recessed portions and the cross sections of the projected portions at the positions of the relevant bottom faces, and P (MPa) is the tight contact pressure between the master carrier and the slave medium (2) at the time of magnetic transfer.
