ABSTRACT:
A master information carrier for magnetic transfer includes a base sheet which is formed of a magnetic material. The master information carrier is provided with an irregularity pattern representing information to be transferred to a magnetic recording medium and a magnetic layer formed along the irregularity pattern. The saturation magnetization Mm of the magnetic layer and the saturation magnetization Ms of the base sheet satisfy the conditionin-line-formulae description="In-line Formulae" end="lead"?1.0<Mm/Ms<100.in-line-formulae description="In-line Formulae" end="tail"?
