MAGNETIC HEAD

摘要

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 golden layers themselves at a low temperature. Then, chromium or titanium is made present between the gold layer and the junction surface to prevent deterioration of magnetic characteristics and generation of false gap and, at the same time, to heighten the junction strength. The thermal diffusion between golden layers themselves is effected at a temperature lower than that of glass fusion to suppress the deterioration of magnetic characteristics, distortion caused by the thermal expansion, and diffusion reaction on the interface. The chromium or titanium layer works to maintain junction strength between the thin magnetic layer or the oxide substrate and the golden layer.
