Flux control effect (FC effect) is one of the field modification effects in microwave-assisted magnetic recording heads by locating the spin torque oscillator in the write gap (WG). In this article, we propose a flux control writer (FC writer) that maximizes the FC effect by flipping the magnetization in the WG with respect to the gap field. In the FC writer, the field gradient gain is emphasized when compared with the amplitude gain. The bit error rate is also improved by about −0.2 compared with a conventional writer at the same erase width. These results indicate that the improvement of recording properties may be possible on any media using FC writer.

磁通控制效果显着的MAM​​R的设计和数值研究头：FC Writer

磁通控制效应（FC效应）是微波辅助磁记录头通过将自旋转矩振荡器置于写入间隙（WG）中而产生的磁场修正效应之一。在本文中，我们提出了一种磁通量控制写入器（FC writer），该函数通过相对于间隙场翻转WG中的磁化强度来最大化FC效应。在FC写入器中，与幅度增益相比，场梯度增益得到了强调。与相同写入宽度下的传统写入器相比，误码率也提高了约-0.2。这些结果表明，使用FC Writer可以在任何媒体上提高记录性能。
