Abstract
In a magnetic head of the metal-in-gap type, a magnetic metal layer provided in a magnetic gap comprises a plurality of thin film layers. Of the thin film layers, one which is located on the side of the magnetic gap is formed by use of a material having a comparatively higher saturation magnetic flux density whereas one which is located on the side of facing the magnetic core is formed by use of a material having a comparatively lower saturation magnetic flux density. Magnetic recording efficiency can be thereby enhanced, without a considerable increase in the thickness of the magnetic metal layer provided in the magnetic gap.
