Abstract
An apparatus includes a write pole that stores data on tracks on a data storage medium. The apparatus also includes side shields on first and second sides of the write pole, and a trailing shield above the write pole and above the side shields. The apparatus further includes a microwave assisted magnetic recording oscillator having conductive pads that form capacitors with portions of a conductive film of the data storage medium. The conductive pads are positioned on a medium-facing surface of a slider that includes the write pole, the side shields and the trailing shield.
