Title: Judy M Ekern: Innovator in Magnetic Transducer Technology
Introduction
Judy M Ekern is a notable inventor based in Edina, MN (US), recognized for her contributions to the field of magnetic transducer technology. With a total of two patents to her name, she has made significant advancements in the design and manufacturing processes of magnetic components.
Latest Patents
One of her latest patents is for a laminated magnetic transducer. This invention includes a laminate forming an I-core, which has 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. Additionally, a C-core member comprises a unitary magnetic body with a second surface confronting the first surface, separated by a non-magnetic gap. An electrical coil or winding is wrapped around at least a portion of the laminate, and in the preferred embodiment, lands are formed of the C-core to create a slider for the transducer.
Another significant patent is for a method of manufacturing a magnetic head core with a flux gap. This process involves assembling the I-core and C-core elements of a ferrite magnetic transducer core. It includes steps such as depositing a gap material on the gap face of one core element and sputter depositing a magnetic material that can be bonded to ferrite by heat and pressure. The surface of the magnetic material is then juxtaposed to the gap face of the other element, and heat and pressure are applied to diffusion bond the two elements together. This method allows for the use of high permeability materials to enhance the core's performance.
