ABSTRACT:
Thin-film magnetic head including an inductive transducing element (15) and a face (3) for magnetic flux coupling of the transducing element with a magnetic recording medium. A first magnetically permeable layer (5) and a second similar layer (7) together constitute a transducing gap (11). To improve the transducing function a layer (21) of a superconducting material is provided between the layers (5) and (7).
