Abstract

A thin film transducer/transformer assembly includes a thin film magnetic transducer assembly formed at a first location on a support surface of a substrate and a thin film transformer assembly formed at a second location of the support surface of the substrate. The transducer assembly and the transformer assembly are each provided with electrically conductive coils which are mutually coupled by electrically conductive paths extending therebetween. The transducer assembly includes a bottom pole member, a top pole member and an electrically conductive coil partially located between the top and bottom pole members. The pole members are mutually coupled at the back gap regions thereof and have pole ends which are mutually spaced and insulated. The transformer assembly includes a bottom pole member, a top pole member forming a closed magnetic path with the bottom pole member, the top and bottom pole members fabricated of a magnetically permeable material, and an electrically conductive coil positioned between the top and bottom pole members. The coil has a pair of ends and a tap connection located between the ends. The pole members are mutually coupled at opposing ends and centrally thereof by means of a downwardly depending central portion extending from the top pole member to the intermediate portion of the bottom pole member. The transducer coil and the transformer coil are electrically coupled in such a way that the output signal supplied by the transformer coil is an electrically boosted signal of greater amplitude than the signal generated by the transducer coil.
