ABSTRACT:
A method for manufacturing a master used for a magnetic transfer, the method including the following steps: A first-master manufacturing step of manufacturing a first master including a predetermined magnetic pattern based on magnetic information; a magnetic-pattern transferring step of transferring the magnetic pattern to a magnetic recording medium by using the first master; an error confirming step of confirming an amount of a transfer error between the magnetic pattern transferred to the magnetic recording medium and the predetermined magnetic pattern; and a second-master manufacturing step of manufacturing a second master as an authentic master based on a correction magnetic pattern so formed as to offset the amount of the transfer error.
