Inductive write head formed with flat yoke and merged with magnetoresistive read transducer

Image Number 15 for United States Patent #6043959.

A magnetic head includes aligned pole tips and a coil proximally disposed between a pair of first and second magnetic yoke layers which define a closed magnetic path with a transducing gap. The second magnetic yoke layer includes a flat geometry with a substantially level cross-sectional profile. The second yoke layer with less curvature results in less mutual inductance with the coil. Furthermore, the coil can be closely positioned between the first and second yoke layer, thereby allowing the coil to be more efficient in inducing magnetic flux in the yoke layers during data writing, and allowing the intercepted flux to induce current into the coil during data reading if the magnetic head is used as an inductive head.
