Abstract
A head assembly having a sensor element on the head assembly. Embodiments of the sensor element are configured to detect non-contact induced head-media interface instability, 'onset of contact' or low level interference. The non-contact head-media instability or interference is detected based upon sensor feedback relating to excitation of the air bearing resonance modes of the slider body. In embodiments of the present invention, the sensor head assembly includes a microactuator which is energizable to microactuate the head or transducer elements on the head assembly.
