摘要： Disclosed herein is a data storage device comprising a slider comprising 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 (a) couple a slider bias voltage to a body of the slider to control a potential of the slider, and (b) provide a signal to the embedded contact sensor. The slider may also include a shunt circuit for mitigating radio-frequency interference by shunting it to ground. The slider may include a write element, which may include a write-field enhancement structure. The slider may include a read element for reading from a recording media.

摘要： Disclosed herein are circuits, architectures, and methods that provide for the control of a data storage device write head's trailing shield and main pole potential with respect to the disk using circuitry that is integrated with circuitry used to bias a spin torque oscillator (STO) apparatus. Various embodiments include slider connections with STO bias circuitry that resides in a read/write integrated circuit, which has a programmable circuit that generates a bias current with overshoot (bias kicks). Also disclosed are circuits that may be incorporated into a slider to mitigate radio-frequency interference.
