摘要： A master information carrier for magnetic transfer includes a master substrate made of metal, including an embossed pattern corresponding to information to be transferred. The master substrate is produced by laminating a metal disk with a predetermined thickness on an original disk, on which an embossed pattern is formed, by electroforming, peeling off the metal disk and die-cutting a disk in a desired size. An outer diameter of the metal disk is at least 1.7 times longer than an outer diameter of the die-cut master substrate. When the metal disk is peeled off from the original disk, deformation due to the forces acting from the side of the outer circumference is reduced. The flatness of the metal disk is ensured and the transfer qualities are improved. Further, a step of removing distortion of the metal disk, caused at the time of peeling off the metal disk, may also be provided.

摘要： A master information carrier for magnetic transfer bears uneven signal patterns on its surface. When the minimum bit length in the uneven signal patterns is Bmin, dummy uneven patterns are provided in a depression of the uneven signal patterns, which has a length of 4Bmin or longer in the direction along a track. When magnetic transfer is performed, magnetized patterns corresponding to the dummy uneven patterns are transferred onto a slave medium. The magnetized patterns are patterns which will not be recognized as reproduction signals at a drive, into which the slave medium after magnetic transfer will be loaded.

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.
