摘要:
A method for producing a magnetic recording medium which includes: forming a magnetic layer on a non-magnetic substrate; forming a dissolution layer on the magnetic layer; forming a mask layer on the dissolution layer; patterning the dissolution layer and the mask layer so as to have a pattern corresponding to a magnetic recording pattern; partially modifying or removing a part of the magnetic layer and the mask layer not covered with the dissolution layer; and dissolving the dissolution layer and removing the dissolution layer together with the mask layer which is on the dissolution layer from the surface of the magnetic layer. The dissolution layer is formed by coating a solution containing an organic silicon compound dissolved in an organic solvent on the magnetic layer, and solidifying the coated chemical solution in the step in which the dissolution layer is formed on the magnetic layer.
