Abstract: The formation of a gap in a magnetic head core or the junction of a thin magnetic film of a metal with an oxide substrate of a magnetic head made of a composite of a thin magnetic film of a metal with an oxide material are conducted by the thermal diffusion between gold layers themselves at a low temperature. Then, chromium or titanium is provided between the gold layer and the junction surface to prevent deterioration of magnetic characteristics and generation of a false gap and, at the same time, to heighten the junction strength. The thermal diffusion between the gold layers themselves is effected at a temperature lower than that of glass fusion to suppress the deterioration of magnetic characteristics, distortion caused by thermal expansion, and diffusion reaction on the interface. The chromium or titanium layer works to maintain function strength between the thin magnetic layer or the oxide substrate and the gold layer.

Abstract: A novel soft magnetic amorphous alloy thin film which, on account of the composition of the film consisting in a combination of a transition metal, a metalloid or semiconducting element, namely B, C or Si and an oxide derived from the starting material, is endowed with a comminuted and dispersed structure of a magnetic amorphous phase and a nonmagnetic amorphous phase. The soft magnetic amorphous alloy thin film may be applied to a magnetic head for short wavelength recording which is required to cope with high frequency characteristics and high coercivity of the recording medium.
