发明名称 Method and system for improving laser alignment and optical transmission efficiency of an energy assisted magnetic recording head
摘要 An EAMR disk drive includes a media, a laser, and a slider coupled with the laser. The laser for provides energy. The slider has an air-bearing surface, a laser input side, an EAMR transducer and an antireflective coating (ARC) layer occupying a portion of the laser input side. The ARC layer is configured to reduce back reflections of the energy. The EAMR transducer includes a write pole, a waveguide optically coupled with the laser and at least one coil. The waveguide has a waveguide input. A portion of the ARC layer resides between the laser and the waveguide input. A method aligns the laser to the ARC layer, and then aligns the laser to the waveguide input. The laser may then be coupled to the slider.
