ABSTRACT:
A soft adjacent layer (SAL) vertically biased magnetoresistive (MR) sensor is disclosed. The SAL biased sensor includes at least three permanent magnet (PM) tabs (hereafter referred to as tabs). An MR sensor layer is disposed in relation to the tabs such that each of the tabs is spaced apart along a width of the MR sensor layer such that each of the tabs is in electrical and magnetic contact with the MR sensor layer to thereby stabilize the MR sensor layer. Preferably, a SAL is disposed in relation to the tabs such that each of the tabs is also spaced apart along a width of the SAL such that each of the tabs is in electrical and magnetic contact with the SAL. A spacer layer is formed between the MR sensor layer and the SAL.
