Abstract
A magnetoresistive read transducer includes a magnetoresistive (MR) layer having end regions spaced by a central active region. A pair of hard magnetic layers provide longitudinal magnetic bias to the MR layer, with each of the hard magnetic bias layers disposed in contact with one of the end regions of the MR layer. A pair of electrical lead members are disposed in contact with the end regions of the MR layer and with the hard magnetic bias layers. The hard magnetic bias layers and the electrical lead members are deposited, followed by selective removal of portions of the lead members to expose the edges of the hard bias material.
