Abstract
A thin-film magnetic head is situated on a carrier (2) on which an electrically conducting plating-base (2) is provided on which by electroplating flux conductors and a magnetically insulating layer (8) are grown. This provides a planar structure on which an electrically insulating layer and a magneto-resistance element are provided. The plating-base also constitutes the gap layer.
Claims8
A thin-film magnetic head, said head including a magnetic carrier, a first magnetically insulating layer provided on said magnetic carrier, flux conductors and a second magnetically insulating layer present on, and directly contacting said first magnetically insulating layer, said second magnetically insulating layer arranged at least partially between said flux conductors, an electrically insulating layer located on said flux conductors and on said second magnetically insulating layer, a magnetic resistance element present on said electrically insulating layer opposite at least said second magnetically insulating layer characterized in that said first magnetically insulating layer is an electrically conducting plating base.
