Abstract
Thin-film magnetic head having a head face (,) and comprising a magnetoresistive element (,) oriented transversely to the head face and a flux-guiding element (,) of a magnetically permeable material terminating in the head face. A peripheral area (,) of the magnetoresistive element extending parallel to the head face is present opposite the flux-guiding element for forming a magnetic connection between the magnetoresistive element and the flux-guiding element. The flux-guiding element and the peripheral area of the magnetoresistive element constitute a common magnetic contact face (,), while the magnetically permeable material of the flux-guiding element is electrically insulating.
