摘要： A perpendicular magnetic write head having a laminated trailing return pole structure that reduces magnetic eddy currents in the return pole for improved write head efficiency. The trailing magnetic return pole includes multiple magnetic layers. Each magnetic layer is separated from an adjacent magnetic layer of the return pole by a non-magnetic layer. The non-magnetic layer terminates at a region that is removed from the air bearing surface in order to allow contact between the magnetic layers at the ABS, thereby preventing stray magnetic fields from emitting from the magnetic layers of the write pole.

摘要： A method for manufacturing a magnetic write pole using a mask that includes a multi-layer hard mask. The multi-layer hard mask hard mask includes a first hard mask layer that is constructed of a Si containing material that can be spun on and a second hard mask material that is deposited by a deposition process such as sputter deposition. The first hard mask layer has optical properties that allow it to function well as a bottom anti-reflective coating (BARC) and also has optical properties that match well with an underlying image transfer layer. The second hard mask material has good selectivity for reactive ion etching so that it functions well as a RIE hard mask.

摘要： A perpendicular magnetic recording system has a write head having a main coil (the write coil) and main pole (the write pole) that directs write flux in a direction perpendicular to the recording layer in the magnetic recording medium, and a transverse auxiliary pole (TAP) that injects auxiliary magnetic flux into the write pole at an angle to the primary or perpendicular axis of the write pole. The additional flux from the TAP, which is injected non-parallel to the primary magnetization of the write pole, exerts a torque on the magnetization of the write pole, thereby facilitating magnetization reversal of the write pole. The TAP is coupled to the main coil but not electrically connected to it. A separate passive coil, not electrically connected to the main coil, may be wrapped as a loop around the main pole and the TAP. Alternatively, the TAP may be located near one of the electrically conductive turns of the main coil.

The lubricant-accumulation barrier is configured to reduce lubricant accumulation on the slider. The lubricant-accumulation barrier also includes a plurality of lubricant-accumulation-barrier portions disposed at a plurality of respective depths below an outer-most surface of a disk-facing side of the slider.

摘要： A method for manufacturing a magnetic write head for perpendicular magnetic recording. The method includes forming a write pole, and then depositing a refill layer. A mask structure can be formed over the writ pole and refill layer, the mask structure being configured to define a stitched pole. An ion milling or reactive ion milling can then be performed to remove portions of the refill layer that are not protected by the mask structure. Then a magnetic material can be deposited to form a stitched write pole that defines a secondary flare point. The stitched pole can also be self aligned with an electrical lapping guide in order to accurately locate the front edge of the secondary flare point relative to the air bearing surface of the write head.

摘要： A thermally assisted magnetic write head having a near-field transducer, a magnetic lip and a diffusion barrier layer between the near-field tranducer and the magnetic lip. The near-field transducer includes a transparent aperture constructed of a material such as SiO2 and an opaque metallic antenna constructed of a metal such as Au formed at a first edge of the aperture. A magnetic lip, connected with the write pole is formed near a second edge of the aperture with a diffusion barrier layer being disposed between the magnetic lip and the aperture. The diffusion barrier layer prevents migration of atomic between the aperture and the magnetic lip, thereby ensuring robust performance at localized high temperatures generated by the near-field transducer.
