摘要：A magnetoresistive (MR) read transducer having passive end regions (50)separated by a central active region (44) in which an MR layer (42) is formed whichextends over substantially only the central active region and in which a hard magneticlayer (46) is formed in each end region. The hard magnetic layers form an abuttingjunction (48) having electrical and magnetic continuity with the MR layer to produce alongitudinal bias in the MR sensor. The transducer is produced by a method in which thesame stencil defines the extent of both the MR layer and the hard magnetic layers sothat the abutting junctions are formed easily and reliably.
