发明名称 Method and apparatus for magnetic transfer, and magnetic recording medium
摘要 A magnetic pattern, in which errors due to sub-pulses do not occur during signal reproduction, is transferred from a magnetic transfer master carrier. A magnetic field is applied to a conjoined body, formed by the master carrier bearing a transfer pattern corresponding to desired information and a discoid transfer medium. A magnetic transfer apparatus that includes magnetic field applying means having magnetic poles that extend from the interior to the outer periphery of the conjoined body, and rotating means for relatively rotating the conjoined body with respect to the magnetic poles is employed. The magnetic poles are provided such that a distance d, between end surfaces of the magnetic poles and the conjoined body decrease from the interior to the outer periphery of the conjoined body. Magnetic transfer is performed employing the magnetic field, the intensity of which increases from the interior to the outer periphery of the transfer medium.
