Abstract: 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.

Abstract: 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.

Abstract: While a heat-assisted, magnetic recording media is not being written to, heat applied from a write head to the recording media to facilitate writing to the recording media is removed. Power is applied to a write coil of the write head to control spacing between the write head and the recording media when the recording media is not being written to.
Abstract translation: 当热辅助磁记录介质未被写入时，从写入头向记录介质施加的热量便于写入记录介质。 当记录介质未被写入时，将功率施加到写入头的写入线圈以控制写入头和记录介质之间的间隔。

Abstract: 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.

Abstract: A magnetic recording head includes a magnetic writer comprising a main write pole and a return write pole. The magnetic recording head includes a write heater assembly comprising at least one first heater subassembly and at least one second heater subassembly. At least part of the magnetic write head is disposed between the first heater subassembly and the second heater subassembly. When the first heater subassembly, the second heater subassembly, and the magnetic writer are energized, a variation in the thermal protrusion of the head media interface of the magnetic recording head may be less than about 20 nm along the down track and/or cross track directions.
Abstract translation: 磁记录头包括一个包括一个主写极和一个返回写极的磁写入器。 磁记录头包括写入加热器组件，其包括至少一个第一加热器子组件和至少一个第二加热器子组件。 磁写头的至少一部分设置在第一加热器子组件和第二加热器子组件之间。 当第一加热器子组件，第二加热器子组件和磁写入器通电时，磁记录头的磁头介质接口的热突起的变化可以沿下轨和/或交叉轨道小于约20nm 方向。
