    摘要: Optical components may be precisely positioned in three dimensions with respect to one another. A bonder which has the ability to precisely position the components in two dimensions can be utilized. The components may be equipped with contacts at different heights so that as the components come together in a third dimension, their relative positions can be sensed. This information may be fed back to the bonder to control the precise alignment in the third dimension.

    摘要: A method and system for providing an energy assisted magnetic recording (EAMR) transducer coupled with a laser. The EAMR transducer has an air-bearing surface (ABS) configured to reside in proximity to a media during use. The EAMR transducer includes a write pole, at least one coil, a waveguide and an output device. The write pole is configured to write to a region of the media. The at least one coil is for energizing the write pole. The waveguide has an input optically coupled to the laser and configured to direct energy from the laser toward the ABS for heating the region of the media. The output device is optically coupled to the waveguide. The output device coupling out a portion of the energy not coupled to the media.

    摘要: A method and system for providing an EAMR transducer is described. The EAMR transducer is coupled with a laser for providing energy and has an ABS that resides near a media during use. The EAMR transducer includes a write pole, coil(s) that energize the pole, a near field transducer (NFT) proximate to the ABS, a waveguide, and a reflector. The write pole has a back gap region and writes to a region of the media. The NFT focuses the energy onto the media. The waveguide directs 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 reflector receives the first portion of the energy from the ABS and reflects a second portion of the energy toward the ABS. The NFT resides between the waveguide and the reflector.

    摘要: A method and system for fabricating an energy assisted magnetic recording (EAMR) transducer is described. The EAMR transducer has an air-bearing surface (ABS) and a waveguide. The method includes providing a planarized near field transducer (NFT) for the waveguide and forming a sloped surface on the planarized NFT. The sloped surface has a front edge separated from the ABS by a distance. The method and system also include providing a write pole on the sloped surface.

    摘要: A well may be formed for access to an optical waveguide core by a process that results in an L-shaped well. The L-shaped well may then be filled with a polymer. By controlling the size of each portion of well, the occurrence of bubbles within the well and cuts to the core may be reduced.
