ABSTRACT:
Thin-film magnetic head comprising a substrate (2), an inductive element (23) and a magnetoresistive element (7), and substantially parallel extending flux guides of a magnetic conducting material for magnetic cooperation with said elements. The flux guides are mutually arranged in such a way that two pairs of flux guides (3A, 3B; 5A, 5B) mutually separated by an insulation layer (19) of a non-magnetic material are present, a first pair constituting a first magnetic circuit, provided with a write gap (27), for the inductive element and a second pair constituting a second magnetic circuit, provided with a read gap (17), for the magnetoresistive element.
