    摘要： A method and system for providing a magnetic recording head is described. The magnetic recording head has an air-bearing surface (ABS) configured to reside in proximity to a media during use. The magnetic recording head includes a main pole, at least one auxiliary pole, a nonmagnetic spacer, and at least one coil. The main pole includes a first main pole piece and a second main pole piece. The first main pole piece includes a pole tip occupying a portion of the ABS and a back edge distal from the ABS. The second main pole piece has a front surface. The auxiliary pole(s) have a front recessed from the ABS and are magnetically coupled with the main pole. The nonmagnetic spacer is between the back edge of the first main pole piece and the front surface of the second main pole piece. The coil(s) are for energizing the main pole.

    摘要： A method and system for providing a magnetic recording head is described. The magnetic recording head has an ABS configured to reside in proximity to a media during use. The magnetic recording head includes a main pole, first and second auxiliary poles, a backgap, a nonmagnetic spacer, and at least one coil. The main pole includes a pole tip occupying a portion of the ABS and a back edge distal from the ABS. Each auxiliary pole has a front recessed from the ABS and a back portion. A portion of the main pole distal from the ABS resides between the auxiliary poles. The auxiliary poles are magnetically coupled with the main pole. The backgap magnetically couples the back portions of the auxiliary poles. The nonmagnetic spacer adjoins the back edge of the main pole and is between the auxiliary poles. The coil(s) energize the main pole.

    摘要： A method and system provide a magnetic transducer having an air-bearing surface (ABS). The magnetic transducer includes a write pole and at least one coil. The write pole has a pole tip and a yoke. The coil(s) energize the write pole. The coil(s) include a plurality of turns a first distance from the pole and at least one additional turn a second distance from the pole. The first distance is different from the second distance. The at least one additional turn extends over at least part of two of the plurality of turns, has a length in a stripe height direction perpendicular to the ABS and has a height in a down track direction. The length is greater than the height.

    摘要： A novel three-terminal MRAM memory cell with an independent sensing and writing paths, a composite data storage layer together with a bias magnetic field for the data storage layer has been invented. The interaction between the magnetic layers within the composite data storage layer is either via Ruderman-Kittel-Kasuya-Yosida (RKKY) coupling, or magnetostatic coupling, or orange peel coupling, or even a direct ferromagnetic coupling. The design improves magnetic and thermal stability of the cell, thus capable for higher area density.
