ABSTRACT:
Electrical connections between the read/write elements on the magnetic transducer head and the circuitry associated therewith (usually an amplifier/driver integrated circuit chip) are provided by means of fine, flat conductive wires encapsulated in a plastic film. At points where the wires need to make substantial angular turns, portions of the plastic film are removed so as to permit such turns to be accomplished without unacceptably increasing the stiffness of the connections which would adversely affect the aerodynamic properties of the transducer head as it "flies" over a spinning magnetic recording disc.
