Abstract
A recording head that includes at least one protection feature that prevents at least one other feature of the recording head from directly colliding with a data storage medium with which the recording head communicates. The recording head includes a transducer element having a leading edge and a trailing edge. The recording head also includes a transducer element heater located closer to the leading edge of the transducer element than the trailing edge of the transducer element. A contact pad is interposed between the leading edge of the transducer element and the transducer element heater to prevent the transducer element from directly colliding with the data storage medium.
