摘要:
A master carrier for magnetic transfer, has: a support having an information writing region where a projection transfer pattern having a first projection is formed, the first projection corresponding to information to be transferred onto a magnetic recording medium; and a magnetic layer on the transfer pattern of the support, wherein the master carrier has a second projection on a surface of the support and the second projection is formed in a region where the information writing region isn't formed to sustain the region where the information writing region isn't formed while the magnetic recording medium and the support are brought into intimate contact with each other.
