Abstract
Disclosed herein is a data storage device comprising a recording media, a slider comprising a write head having a write-field enhancement structure for recording data to the recording media, an electronics module, and a plurality of lines disposed between and coupled to the slider and the electronics module, wherein at least one line of the plurality of lines is configured to both couple a bias voltage to a body of the slider, and carry a bias current for the write-field enhancement structure. Also disclosed herein is a data storage device comprising a slider with an embedded contact sensor, an electronics module, and a plurality of lines disposed between and coupled to the slider and the electronics module, wherein at least one line of the plurality of lines is configured to both couple a bias voltage to a body of the slider, and provide a signal to the embedded contact sensor.
