Abstract
Embodiments of the present invention generally relate to a MAMR head. The MAMR head includes an STO and an embedded contact sensor (ECS). The STO and the ECS are electrically connected in series and are connected to the same terminals. During operation, the current applied to the STO is controlled with respect to a change in resistance of the ECS.
