A recording head comprises a write pole extending to an air-bearing surface. A near-field transducer is positioned proximate a first side of the write pole in a down-track direction. A heatsink structure is proximate the near-field transducer and positioned between the near-field transducer and the write pole. The heatsink structure extends beyond the near-field transducer in a cross-track direction and extends in a direction normal to the air-bearing surface.

Heatsink structures for heat-assisted magnetic recording heads

A magnetic recording head includes an active component and a piezoelectric actuator. The active component is disposed proximal to a media-facing surface of the magnetic recording head. The piezoelectric actuator includes a piezoelectric layer, a first electrode coupled to the piezoelectric layer, and a second electrode coupled to the piezoelectric layer. The piezoelectric actuator is configured to exert a mechanical force to displace the active component such that the displacement changes a protrusion of the active component from the media-facing surface.

A recording head includes one or more transducer elements, and an electrically insulative layer encasing the one or more transducer elements. The recording head also includes a substrate below the electrically insulative layer. The recording head further includes a heat sinking layer between the electrically insulative layer and the substrate.

An apparatus comprises a slider comprising an air bearing surface (ABS). The slider comprises a reader, a writer, and a reader heater. The reader heater is configured to cause a protrusion of the ABS proximate the reader, and the reader heater comprises a first planar loop and a second planar loop, wherein the first and second loops are in the same plane.

Double loop heater

Described are magnetic recording heads that include a read transducer and a write transducer, with the two transducers being arranged in a side-by-side configuration.

A slider comprises an air bearing surface (ABS) and is configured to interact with a magnetic recording medium. A writer is provided on the slider and comprises a write coil having a media-facing surface situated at the ABS. Cooling arms project laterally from peripheral surfaces of the write coil and extend along the ABS. The media-facing surface of the write coil and the cooling arms are exposed to the ABS to facilitate increased cooling of the write coil at the ABS.

Write coil cooling arrangement at air bearing surface

A slider is configured to interact with a magnetic recording medium and comprises an air bearing surface (ABS). A writer is provided on the slider and comprises a write pole terminating at or near the ABS, a return pole proximate the write pole, and a write coil arrangement provide around the write pole. The write coil arrangement comprises lower and upper write coils each having a generally circularly-shaped periphery, and a plurality of spaced-apart cooling fins connected to and projecting outwardly from the periphery of each of the lower and upper write coils.

A recording head that includes at least one protection feature that prevents at least one other feature of the recording head from directly colliding with a data storage medium with which the recording head communicates. The recording head includes a transducer element having a leading edge and a trailing edge. The recording head also includes a transducer element heater located closer to the leading edge of the transducer element than the trailing edge of the transducer element. A contact pad is interposed between the leading edge of the transducer element and the transducer element heater to prevent the transducer element from directly colliding with the data storage medium.

Contact pad for recording heads

A media-facing surface of a magnetic head is positioned proximate a moving magnetic recording medium. A current is applied to an electromagnet of the magnetic head. The current induces a magnetic force between the magnetic head and the magnetic recording medium that adjusts a clearance therebetween.

A magnetic head includes a read transducer and a write transducer at a media-facing surface of the magnetic head. The magnetic head includes at least one heater that causes heat deformation at the media-facing surface in response to different first and second energizing currents. The first energizing current results in a first close point between the media-facing surface and a recording medium. The second energizing current results in a second close point between the media-facing surface and the recording medium. The second close point is at a different location in the media-facing surface than the first close point.
