| 1. A head assembly comprising:
a slider body including a leading edge and a trailing edge;
at least one transducer element along the trailing edge of the slider body;
a sensor element fabricated along a trailing edge portion of the slider body configured to detect low frequency excitation
of the slider body in a frequency range of approximately less than about 1.0 MHz and the sensor element being positioned closer
to the leading edge of the slider body than the at least one transducer element; and
a microactuator between the sensor element and the at least one transducer element and configured to adjust the at least one
transducer element in a z-height direction.
