Retrofits in transducer device aperfeicoado to express how different values of resistance to different intensity of the field magnetically responsive.The head and process for manufacturing it and process for detecting in the form of magnetically recorded information fields.

摘要

A magnetic transducer exhibiting the magnetoresistive (MR) effect includes at least two thin film layers. An MR film in electrical control with a higher resistivity layer is magnetically biased by a portion of the MR sense current shunted through the nonmagnetic layer.
