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.

A data storage device comprising:
- a slider comprising:
- a write pole configured to store data on tracks on a data storage medium;
- side shields on first and second sides of the write pole;
- a trailing shield above the write pole and above the side shields;
- and
- conductive pads attached to the slider and configured to form capacitors with portions of a conductive film of the data storage medium.
An apparatus comprising:
- a write pole configured to store data on tracks on a data storage medium;
- side shields on first and second sides of the write pole;
- a trailing shield above the write pole and above the side shields;
- and
- a microwave assisted magnetic recording oscillator comprising conductive pads that are configured to form capacitors with portions of a conductive film of the data storage medium, the conductive pads being positioned on a medium-facing surface of a slider that includes the write pole, the side shields and the trailing shield.
A method comprising:
- forming a write pole over a substrate that is a portion of a slider, the write pole being capable of storing data on tracks on a data storage medium;
- forming side shields on first and second sides of the write pole;
- forming a trailing shield above the write pole and above the side shields;
- and
- forming conductive pads on a medium-facing surface of the slider, the conductive pads are electrically isolated from each other and are formed as a part of a microwave assisted magnetic recording oscillator.
