Manufacturing method of recording medium, electric/magnetic field copy master and electric/magnetic field copying device

When copying servo information from an electro-magnetic field copy master to a vertical storage medium, the magnetization direction of the vertical storage medium is made to the direction the reverse of an external electro-magnetic field applied to the vertical storage medium and the electro-magneti...

description When copying servo information from an electro-magnetic field copy master to a vertical storage medium, the magnetization direction of the vertical storage medium is made to the direction the reverse of an external electro-magnetic field applied to the vertical storage medium and the electro-magnetic field copymaster, the vertical storage medium is closely touched on the electromagnetic field copy master provided with a substrate which has concavity/convexity corresponding to the servo information and at least the convex part of which of the concavity/convexity is made of a softly magnetic material and a conductor installed in the concave part of the substrate and an external electro-magnetic field stronger than the coercive field strength of the vertical storage medium is instantaneously applied to the vertical storage medium and the electromagnetic field copy master.
