Abstract: PURPOSE:To impart magnetic anisotropy to a magnetic layer and further to improve the adhesion rate and the adhesion efficiency with respect to the amt. of the target to be used by diagonally projecting ions to a target surface and diagonally projecting the released sputtering atoms to a magnetic disk substrate. CONSTITUTION:Working gaseous ions are diagonally projected to the target 11 surface and the sputtering atoms released by the diagonal incidence of the working gaseous ions are diagonally projected to the magnetic disk substrate 12 disposed in parallel with the target surface 11a. The magnetic anisotropy is generated in the magnetic disk substrate 12 by the diagonal incidence of the sputtering atoms, by which the magnetic characteristics are improved. A mask for regulating the flying of the sputtering atoms released from the target surface 11a to the magnetic disk substrate 12 is not interposed between the target surface 11a and the substrate 12 and, therefore, the adhesion efficiency and adhesion rate of the sputtering atoms to the magnetic disk are improved.
