ABSTRACT:
A magnetic head includes an inductive coil electrically partitioned into a plurality of segments by a plurality of conductive leads. During the data reading mode, magnetic flux changes emanating from a record medium are sensed by the magnetic head. The inductive coil transduces the magnetic flux changes into electrical signals at the conductive leads. The signals are amplified by serially cascading the plurality of segments and the signals are then fed into amplifiers. During the data writing mode, the electrical signal is applied to two of the conductive leads via a data writing amplifier. The inductive coil converts the electrical signal into changes in magnetic flux for recording onto a magnetic medium.
