摘要:
A disclosed method for manufacturing a magnetic recording medium includes a first step of forming a magnetic recording film on a non-magnetic substrate and a second step of forming, in the magnetic recording film, a magnetic recording region which is magnetically recordable and an isolation region which is magnetically non-recordable and includes a first isolation-region portion and a second isolation-region portion. The second step includes the sub-steps of performing first ion implantation on the magnetic recording film to form the first isolation-region portion along a boundary of the isolation region to be formed with the magnetic recording region to be formed; and performing second ion implantation on the magnetic recording film to form the second isolation-region portion in the surface of the isolation region to be formed.
