摘要	A method of manufacturing a thermally-assisted magnetic head includes providing a light source unit including a laser diode; providing a reflection board, and a photo detector; driving the laser diode to emit a light beam towards the reflection board; performing an alignment between the light source unit and the thermally-assisted magnetic recording head section, based on a reflected light of the light beam reflected by the reflection board, then passed through the optical waveguide and finally detected by the photo detector obtaining the maximum power in a LED emission state of the laser diode; and bonding the light source unit to the slider after the alignment is completed. It improves alignment accuracy between a light source unit and a slider during a bonding process therebetween, prevents a laser diode of the light source unit instability, and improves performance of the thermally-assisted magnetic head finally.
其他摘要	一种制造热辅助磁头的方法，包括提供包括激光二极管的光源单元;提供反射板和光电探测器;驱动激光二极管向反射板发射光束;基于由反射板反射的光束的反射光，在光源单元和热辅助磁记录头部分之间进行对准，然后通过光波导，最后由光电检测器检测，获得最大功率在激光二极管的LED发光状态下;在对齐完成后将光源单元粘合到滑块上。它提高了光源单元和滑块之间的键合过程中的对准精度，防止了光源单元的激光二极管不稳定，并最终提高了热辅助磁头的性能。
