ABSTRACT:
For providing a magnetoresistive read transducer capable of increasing the output by the increase of current, reduced with noises and having a durability, a magnetoresistive read transducer comprising a substrate and laminated thereon, a lower shield, a first gap layer, a thin film magnetoresistive element portion, a longitudinal bias layer, an electrode portion and an upper shield, each in a predetermined pattern successively, in which the entire resistance value of the electric conduction including the contact resistance of the electrode portion 7 is set within 1.2 times of a theoretical resistance value calculated based on the specific resistivity of the layer, in which a polysilicon layer is laminated between the magneto resistive film and the longitudinal bias layer.
