Abstract
A disc drive includes a disc, a beam extending from the voice coil motor to a gimbal point to provide a load force, and a slider that flies over the disc with a pole tip protrusion that has an ambient temperature sensitivity. The disc drive also includes a strut with a yielding bend section (YBS). Deposits of shape memory alloys (SMA) having different first and second transformation temperature ranges are deposited on the yielding bend section (YBS) and effectively reduce an ambient temperature sensitivity of the pole tip protrusion.
