Abstract
An inverted hybrid type thin film magnetic head includes a substrate, an inductive recording element and a magnetoresistive reading element. The inductive recording element has a first magnetic film provided on an inner surface of a recessed portion formed in the surface of the substrate and on the surface of the substrate to constitute a pole portion, a thin film coil, a gap film formed on the pole portion of the first magnetic film and on an insulating film which supports and isolates coil turns, and a second magnetic film applied on the gap film and having a pole portion opposed to the pole portion of the first magnetic film via the gap film. The magnetoresistive reading element includes a magnetoresistive film formed within a shield gap film provided on the second magnetic film and a third magnetic film formed on the shield gap film.
