  • Thin film magnetic head having polymer on broken flux guide sections, method of producing and integrated structure incorporating same
    Patent number: 5646804
    Abstract: In a thin film magnetic head comprising a magnetoresistive sensing element (MRE) located inwardly from the head face, a first section of a broken flux guide extending inwardly from the head face to overlie one peripheral edge portion of the MRE, and a second section overlying an opposite peripheral edge portion of the MRE, the space overlying the MRE between the flux guide sections is filled with a poller such as a photoresist, providing a smooth surface for a test/bias conductor, reducing shorts due to inadequate step coverage, and providing mechanical stress relief, leading to improved stability of the MRE.
