Magnetic recording medium and manufacturing method thereof

摘要

A magnetic recording medium and a manufacturing method thereof can be formed or carried out without substrate heating. The magnetic recording medium has a seed layer of a nonmagnetic material having a bcc structure that has (211) orientation formed on a nonmagnetic substrate, an underlayer of a nonmagnetic material having a bcc structure that is different to that of the seed layer 102 and having (211) preferential orientation formed on the seed layer, an intermediate layer of a nonmagnetic material having an hcp structure that has (100) preferential orientation formed on the underlayer, and a magnetic layer of an hcp CoCr alloy that has (100) preferential orientation formed on the intermediate layer.
