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.

Abstract: A process for assembling the I core and C core element of a ferrite magnetic transducer core includes the steps of depositing by sputtering a gap material on the gap face of one core element. A magnetic material of the type which can be bonded to ferrite by heat and pressure is then sputter deposited on the gap material. The surface of the magnetic material is then juxtaposed to the gap face of the other element and heat and pressure below a pint which may affect the ferrite's magnetic characteristics is used to diffusion bond the two elements to each other. It is possible to use a layer of Sendust Fe-Si-Al high permeability alloy or other high permeability material as the magnetic material deposited on the gap material if this enhancement of the core is desired. In any case, higher than customary clamping pressure along with lower than customary temperature is used to effect the bond.
