    • The present invention provides a method of manufacturing a master disk for magnetic transfer, comprising the steps of: forming a metal plate having a predetermined thickness on an original plate having a concavo-convex pattern corresponding to information to be transferred; stamping the metal plate separated from the original plate to form a center opening and a circular rim, thereby providing a master substrate; and depositing a magnetic layer on the concavo-convex pattern of the master substrate, wherein a region at the upper edge of the center opening where a roll off occurs when the center opening of the master substrate is formed by stamping is defined as a center-opening roll-off region, a predetermined range of center-opening buffer region is provided outside of the center-opening roll-off region, and the concavo-convex pattern is formed outside of the center-opening buffer region.
    • 本发明提供一种制造用于磁转移的母盘的方法,包括以下步骤:在具有对应于要传送的信息的凹凸图案的原版上形成具有预定厚度的金属板; 冲压与原版分离的金属板,形成中心开口和圆形边缘,从而提供主基板; 并且在母基板的凹凸图案上沉积磁性层,其中当通过冲压形成母版基板的中心开口时,在中心开口的上边缘处发生滚落的区域被定义为中心开口, 开口滚降区域,中心开口缓冲区域的预定范围设置在中心开口滚降区域的外侧,并且凹凸图案形成在中心开口缓冲区域的外部。
