摘要： A method and system provide a magnetic transducer including first and second read sensors, a shield and a conductive via. The shield is between the first and second read sensors. In one aspect, the magnetic transducer also includes first and second read shields. In this aspect, the first read shield has a read shield aperture. The conductive via extends through the read shield aperture, provides electrical contact to the shield and is insulated from the first read shield. In another aspect, the shield has first and second shield layers separated by an insulating layer. In this aspect, the second shield layer has an aperture therein. The conductive via extends through this aperture, provides electrical contact to the first shield layer and is insulated from the second shield layer.

摘要： A heat-assisted magnetic recording (HAMR) transducer is coupled with a laser for providing energy and has an air-bearing surface (ABS) configured to reside in proximity to a media during use. The HAMR transducer includes a write pole, at least one coil, a waveguide optically coupled with the laser and a grating. The write pole is configured to write to a region of the media. The coil(s) energize the write pole. The waveguide includes arms that have an optical path difference. The grating is optically coupled with the laser. The waveguide is optically coupled with the grating and receives light from the grating.

摘要： A method and system provide a magnetic transducer having an air-bearing surface (ABS) and including first and second read sensors and a shield. The shield is in a down track direction from the first read sensor and between the first and second read sensors. The shield includes a first shield layer, a second shield layer and an insulating layer between the first and second shield layers. The first shield layer is between the first read sensor and the second shield layer. The second shield layer is between the first shield layer and the second read sensor. The first shield layer has a first footprint. The second shield layer has a second footprint. The second shield layer overlaps the first shield layer in the down track direction. The overlap is not more than fifty percent of the first footprint and not more than fifty percent of the second footprint.
