Substrate Manufacturing Method, Substrate Manufactured by the Substrate Manufacturing Method and Magnetic Recording Medium Using the Substrate

摘要

Disclosed is a method for manufacturing a substrate provided with a surface portion having a plurality of concave and convex configurations. The method includes a step of applying a solution between a mold having a configuration corresponding to the concave and convex configurations, and a substrate base member, the solution obtained by dissolving a constructional material for composing the surface portion in a solvent; a step of forming the surface portion by drying the solvent in a state that the solution is applied between the mold and the substrate base member; and a step of releasing the mold from the surface portion. The mold satisfies requirements that a contact angle of a contact portion of the mold to be contacted with the solution is smaller than 90° with respect to the solvent, and that a work of adhesion between the contact portion and the constructional material is smaller than a work of adhesion between the contact portion and the solvent.
