Abstract
A data storage device may be generally directed to a data transducing head capable of magnetoresistive data reading. Such a data transducing head may be configured with at least a trilayer reader that contacts and is biased by a coupling feature. The coupling feature may have a smaller extent from an air bearing surface (ABS) than the trilayer reader.

- 9. A transducing head comprising a coupling feature disposed between and coupling a trilayer reader to a magnetic shield, the coupling feature having a smaller perpendicular extent from an air bearing surface (ABS) than the trilayer reader to define a non-magnetic bevel region between the trilayer reader and magnetic shield, distal the ABS.
- 14. A data storage device comprising a trilayer reader respectively coupled to and biased by first and second magnetic shields via first and second coupling features, the first and second coupling features each contacting the trilayer reader with smaller extents from an air bearing surface (ABS) than the trilayer reader.
