Abstract
An apparatus comprises a microwave-assisted magnetic recording slider body. The body includes a write pole, a trailing shield, a spin torque oscillator, and an amplifying structure. The write pole extends from the air bearing surface into the slider body for a first distance, and the trailing shield extends from the air bearing surface into the slider body for a second distance. The spin torque oscillator is disposed proximate and between the write pole and the trailing shield at the air bearing surface and extends into the slider body for a third distance that is less than the first and second distances. The amplifying structure comprises a stepped portion and a gap, is recessed from the air bearing surface and disposed proximate the spin torque oscillator. The gap has a first interface with the write pole and a second interface with the trailing shield, wherein at least one of the first and second interfaces forms the stepped portion.
