A heat-assisted magnetic recording head includes a write pole tip that extends to a media-facing surface and a heat sink that is thermally coupled to a side of the write pole tip. A surface plasmonic plate is in contact with a side of the heat sink that faces away from the write pole and is recessed from, the media-facing surface. A nanorod extends from a surface of the surface plasmonic plate and towards the media-facing surface.

A manufacturing method for a magnetic head includes the steps of: forming a main pole; forming a spin torque oscillator; and forming a trailing shield. The step of forming the spin torque oscillator includes: a step of forming a layered film; a step of forming an interposition layer; a step of forming a mask; a first etching step of etching a portion of the interposition layer using the mask; a second etching step of etching a portion of the layered film using the mask and the interposition layer as an etching mask; a step of removing the interposition layer and the mask; and a patterning step of patterning the layered film into the spin torque oscillator.

A perpendicular magnetic recording write head includes a heater on one side of the pole tip of the main pole and a heat sink on the opposite side of the pole tip. The heater is formed of high resistivity material and is connected to a power source. During writing, power is applied to the heater, which causes a relatively large temperature gradient across the pole tip from the heater to the heat sink. The temperature gradient increases the damping of the ferromagnetic material of the main pole during writing, which increases the switching speed of the main pole.

The present disclosure generally relates to data storage devices, and more specifically, to a magnetic media drive employing a magnetic recording head. The head includes a trailing shield, a main pole, an STO disposed between the trailing shield and the main pole, and a non-magnetic conductive structure adjacent to the main pole and in contact with the STO. The STO includes an FGL and an SPL, and the FGL is disposed between the main pole and the SPL. The FGL includes a side extending over the main pole and at least a portion of the non-magnetic conductive structure. With the FGL disposed proximate to the main pole and over at least a portion of the non-magnetic conductive structure, current crowding and disturbance from the trailing shield are minimized.
