The examination of the effect of exchange field Hex on media properties and the dependence of Hex on composition of stabilizing layers and sputtering process in SF media was presented. Non-textured NiP/Al substrate was used to grow the SF media by DC magnetron sputtering method. The results revealed that to increase Hex, it was necessary to reduce the interface roughness and increase the saturation magnetization of the ferromagnetic layers.
