摘要:
There is provided a method of manufacturing a magnetic recording medium where a magnetic layer is formed on a substrate, followed by formation of a magnetic pattern, which is a method producing few defective products with low production cost, the method of manufacturing a magnetic recording medium having magnetic recording patterns which are magnetically separated, including, in the following order: a step of forming a magnetic layer on a substrate which has an opening in the centre; a step of applying a resin film to the magnetic layer; a step of pressing against the substrate a film-type mold on which an uneven pattern has been formed; a step of transferring the uneven pattern of the mold onto the resin film; a step of separating the mold from the substrate; and a step of forming magnetic recording patterns on the magnetic layer using the uneven pattern which has been transferred.
