Abstract:
A thin film magnetic head comprising:lower and upper magnetic cores provided face-to-face via a non-magnetic thin film serving as a magnetic gap;at least two layers of multi-layer thin film coils insulated from each other via an insulating resin layer between said magnetic cores and comprising thin film conductors wound on said magnetic cores and having a substantially rectangular cross section;the thin film conductors of a thin film coil of at least one layer, other than the lowermost layer, of said multi-layer thin film coils having a downward convex bottom surface;the thin film conductors of a thin film coil of a layer immediately below said thin film coil whose thin film conductors have the downward convex bottom surface having an upward convex top surface; andthe thin film conductors of said upper-layer thin film coil being disposed face-to-face in between the adjoining thin film conductors of said lower-layer thin film coil in the longitudinal section in the gap depth direction of said head.
