ABSTRACT:
A magnetic transducer includes a laminate forming an I-core having a layer of magnetic material deposited between first and second non-magnetic substrates. The layer of magnetic material is generally perpendicular to and extends to a first surface of the I-core. A C-core member comprises a unitary magnetic body having a second surface confronting the first surface. A non-magnetic gap is between the first and second surfaces. An electrical coil or winding is wrapped around at least a portion of the laminate. In the preferred embodiment, lands are formed of the C-core to form a slider for the transducer.
