Abstract:
1. A method to fabricate a tunneling magnetoresistive (TMR) read transducer, comprising the acts of: depositing an insulative layer on a wafer substrate; depositing a bottom lead over the insulative layer; depositing a laminated TMR layer over the bottom lead, the laminated TMR layer comprising a plurality of laminates; defining a TMR sensor having a stripe height in the TMR layer; defining a parallel resistor in the TMR layer; defining first and second shunt resistors in the TMR layer; depositing a top lead over the TMR sensor; electrically connecting the parallel resistor to the bottom lead and to the top lead; electrically connecting the first shunt resistor to the bottom lead and the wafer substrate; electrically connecting the second shunt resistor to the top lead and the wafer substrate.
