ABSTRACT:
In the method for making the magnetic recording wherein a first magnetic layer is formed on a substrate and a second magnetic layer is formed on the first magnetic layer, before forming the second magnetic layer, accelerated ions are irradiated onto a surface of the first magnetic layer. Thereby, naturally formed oxidized layer and adhered impurity on the first magnetic layer are removed from the surface of the first magnetic layer by ion etching action by the irradiation of ions, and hence a preferable condition of an interface between the first magnetic layer and subsequently formed second magnetic layer is obtained.
