    摘要: A method of forming a near field transducer (NFT) for energy assisted magnetic recording is disclosed. A structure comprising an NFT metal layer and a first hardmask layer over the NFT metal layer is provided A first patterned hardmask is formed from the first hardmask layer, the first patterned hardmask disposed over a disk section and a pin section of the NFT to be formed. An etch process is performed on the NFT metal layer via the first patterned hardmask, the etch process forming the NFT having the disk section and the pin section.

    摘要: A method provides an EAMR transducer. The EAMR transducer is coupled with a laser and has an ABS configured to reside in proximity to a media during use. The EAMR transducer includes an NFT for focusing the energy onto the media. A sacrificial layer is deposited on the NFT and a mask having an aperture provided on the sacrificial layer. A portion of the sacrificial layer exposed by the aperture is removed to form a trench above the NFT. A heat sink is then provided. At least part of the heat sink resides in the trench. The heat sink is thermally coupled to the NFT. Optical material(s) are provided around the heat sink. A write pole configured to write to a region of the media is also provided. The write pole is thermally coupled with the top of the heat sink. Coil(s) for energizing the write pole are also provided.

    摘要: A read sensor for a transducer is fabricated. The transducer has a field region and a sensor region corresponding to the sensor. A sensor stack is deposited. A hybrid mask including hard and field masks is provided. The hard mask includes a sensor portion covering the sensor region and a field portion covering the field region. The field mask covers the field portion of the hard mask. The field mask exposes the sensor portion of the hard mask and part of the sensor stack between the sensor and field regions. The sensor is defined from the sensor stack in a track width direction. Hard bias layer(s) are deposited. Part of the hard bias layer(s) resides on the field mask. Part of the hard bias layer(s) adjoining the sensor region is sealed. The field mask is lifted off. The transducer is planarized.

    摘要: A method and system for providing an optical grating are described. The optical grating is configured for light of a wavelength and includes a first optically transparent layer, a stop layer on the first optically transparent layer, and a second optically transparent layer on the stop layer. The first optically transparent layer is continuous and includes a material. The second optically transparent layer also includes the material. The second optically transparent layer also includes a plurality of discrete ridges spaced apart by a pitch. The stop layer is configured to be invisible to the light.
