Zusammenfassung:	Magnetic transducing heads capable of reading and writing magnetic information in the form of a pattern of magnetization on a magnetic recording medium are provided utilizing a unitary structure of magnetic sheet metal foil and conductive, non-magnetic metal foil and thin film deposition techniques. In the preferred embodiment, the transducing heads consist of a monolithic sandwich of thin metallic magnetic foil forming a magnetic core enclosing a conductive non-magnetic metal foil exciting winding.
