Spin wave assisted MAMR recording head

A magnetic recording device, comprising:

• a main pole, the main pole comprising a contact recessed from a media facing surface (MFS) and a contact terminal coupled to the contact, wherein the contact is disposed perpendicular to a longitudinal axis of the main pole;
• a trailing shield disposed adjacent to the main pole;
• a spin torque oscillator (STO) device disposed between the main pole and the trailing shield at the MFS;
• a leading shield disposed adjacent to the main pole, the leading shield being disposed between the contact and the MFS;
• a first alternating current (AC) power source coupled to the contact terminal;
• and
• a second AC power source coupled to the trailing shield.
