The present invention relates to a master information carrier for magnetically transferring desired information onto a slave medium, the master information carrier for magnetic transfer comprising uneven signal patterns corresponding to the desired information, which are formed along a track, characterized in that when a minimum bit length in the uneven signal patterns is B min , dummy uneven patters, which are different from the uneven signal patterns, are formed in a depression of the uneven signal patterns, which has a length of 4B min or longer in the direction along the track, wherein the dummy uneven patterns are patterns for transferring magnetized patterns, which will not be detected by a magnetic head for reproduction in a drive, into which the slave medium after magnetic transfer will be loaded, wherein the dummy uneven patterns are formed in the track so that the ratio between a depression area and a protrusion area in the width direction of the track.is approximately 1 : 1, and the dummy uneven patterns include protrusions and depressions, which are formed in a cycle, obtained by multiplying the width of the track with the reciprocal of an even number.
