摘要： A method and system provide an EAMR transducer having an air-bearing surface (ABS) that resides near a media during use. The EAMR transducer includes a write pole, coil(s), a near field transducer (NFT), a waveguide, and a reflective grating. The write pole writes to a region of the media. The coil(s) energize the write pole. The NFT is proximate to the ABS and focuses the energy onto the media. The waveguide is configured to direct the energy from the laser toward the NFT at an incident angle with respect to the ABS. A first portion of the energy reflects off of the ABS at a reflected angle. The reflective grating receives the first portion of the energy at the reflected angle from the ABS and reflects a second portion of the energy toward the ABS. The NFT resides between at least part of the waveguide and the reflective grating.

摘要： A method of fabricating a magnetic device is described. A mask removing layer is formed on a layered sensing stack and a hard mask layer is formed on the mask removing layer. A first reactive ion etch is performed with a non-oxygen-based chemistry to define the hard mask layer using an imaged layer formed on the hard mask layer as a mask. A second reactive ion etch is performed with an oxygen-based chemistry to define the mask removing stop layer using the defined hard mask layer as a mask. A third reactive ion etch is performed to define the layered sensing stack using the hard mask layer as a mask. The third reactive ion etch includes an etching chemistry that performs at a lower etching rate on the hard mask layer than on the layered sensing stack.
