Patent ID: 7972490

Claim:
A method for manufacturing a magnetic transfer master disk including a protrusion/recess pattern corresponding to information to be transferred, the method comprising: an initial layer forming step of forming an initial layer having conductivity using Ni, Ru, Pt, or alloys of them, on a surface of an inverted-mold master including an inverted protrusion/recess pattern; a principal layer forming step of forming a principal layer having a magnetic property using Co, a Co alloy, Fe, or a Fe alloy, on a surface of the initial layer of the inverted-mold master after formation of the initial layer; an electroforming step of forming a metal layer on a surface of the principal layer of the inverted-mold master via electroforming after formation of the principal layer with a conductive layer including the initial layer and the principal layer as a cathode; and a peeling step of peeling a duplicate, in which the initial layer, the principal layer and the metal layer are integrated, off from the inverted-mold master after the electroforming step, so as to obtain a magnetic transfer master disk, which is the duplicate, in which the principal layer and the initial layer are deposited on a protruded/recessed surface of the metal layer.
