Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method of a substrate for recording medium which can reliably transfer a shape of a mold having a minute shape to the substrate for recording medium. SOLUTION: A method to transfer and form an uneven pattern corresponding to a recording signal on a main surface of a tabular recording medium by molds 2A and 2B is provided with; a process for preparing a pre-transfer substrate 1 comprising a dimension D1 larger than the uneven pattern area D2 corresponding to a recording signal formed in main surfaces of molds 2A and 2B for transfer and a dimension D1 smaller than the dimension D3 specified as a substrate 3 for recording medium; and a transfer process to transfer an uneven pattern by pressing molds 2A and 2B to the pre-transfer substrate 1 and to expand the pre-transfer substrate 1 to the dimension of the substrate 3 for recording medium.
