摘要：
A thin film type magnetic head comprising a magnetic core made of a metallic magnetic material and interposed between two non-magnetic bases is disclosed. An auxiliary film, made of a magnetic material, is disposed on a surface including the magnetic core and not the surface which comes into contact with a recording medium. This arrangement can reduce the size of the magnetic head while preventing the lowering of the reproduction output.
