发明名称 Magnetic recording media and method of forming them
摘要 The present invention is directed to carrying out a high density magnetic recording to a material having a large coercive force by perpendicular magnetic recording head. By giving a patterning onto a soft magnetic under layer of a perpendicular two-layer recording media in sync with a period of a recording bit, a magnetic field from a write head can be allowed to converge to a soft magnetic column. Therefore, a magnetization reversal of the magnetic recording media material having a large anisotropic constant becomes possible, and then a high density magnetic recording can be achieved.
