PURPOSE:To assure an excellent magnetic characteristic by positioning the sliding surface of a substrate which supports a thin ferromagnetic metallic film toward the (1, 1, 0) face from the single crystal manganese-zinc ferrite face and toward the (2, 1, 1) face from the (1, 1, 1) face respectively within specific angles of inclination. CONSTITUTION:A magnetic head is manufactured by using respectively single crystal manganese-zinc ferrite as the core substrate and an amorphous alloy of cobalt-niobium-zirconium as the thin ferromagnetic metallic film. The magnetic head is brought into contact with a magnetic disk while the disk is kept rotated to maintain the continuous sliding contact between the head and disk. As a result, the head is so formed that the sliding surface of the core substrate is positioned within the range of 0-30 angle of inclination from the (1, 1, 1) face toward the (1, 1, 0) face and within the range of 0-30 angle of inclination from the (1, 1, 1) face toward (2, 1, 1) face, then the core substrate and the thin ferromagnetic metallic film wear approximately at the similar rate and therefore the difference of steps between both is extremely small. |
