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.

从磁传输主载波传送在信号再现期间不发生由子脉冲引起的误差的磁图。 将磁场施加到由承载具有对应于期望信息的传送图案的主载体形成的结合体和盘状转印介质。 采用磁性传送装置,其包括具有从结合体的内部延伸到外周的磁极的磁场施加装置,以及用于使结合体相对于磁极相对旋转的旋转装置。 磁极设置成使得磁极端面和结合体之间的距离d从结合体的内部到外周减小。 使用磁场进行磁转移,其强度从转印介质的内部至外周增加。
