Method of producing magnetic disc |
摘要 |
A magnetic disc comprises a non-magnetic underlayer formed on a substantially flat surface of a substrate by growing grains of a magnetic material in a circumferential direction of the magnetic disc, and a magnetic layer formed on the non-magnetic underlayer, where the magnetic easy axis of the magnetic layer is oriented in the circumferential direction of the magnetic disc. A method of producing the magnetic disc forms the magnetic layer so that the magnetic easy axis thereof becomes oriented in the circumferential direction of the magnetic disc.
