摘要:
A master information carrier has on its surface an irregularity pattern representing information to be magnetically transferred to a magnetic recording medium held in contact with the surface of the master information carrier. The parts of the surface of the master information carrier which is brought into contact with the magnetic recording medium are in the range of 0.3 nm to 10.0 nm in center plane mean surface roughness SRa.
