MAGNETIC RECORDING MEDIUM AND INFORMATION RECORDING DEVICE
摘要:
A magnetic recording medium including: a substrate; plural information recording members that are formed of a hard magnetic material on the substrate, in each of which magnetization in a direction crossing the substrate is generated and, when the information recording members pass in a predetermined traveling direction in a magnetic field for information recording, the magnetization is directed to a direction corresponding to a direction of the magnetic field and information is recorded; and a high-permeability film that is placed on an edge on a front side of the information recording members in the traveling direction and has a magnetic permeability higher than a magnetic permeability of the information recording members.
