The invention provides a notched trailing shield that minimizes stray field formation while improving field gradient. The write head having a notched trailing shield is extremely manufacturable, being self aligned with the write pole of the perpendicular write head and using presently existing manufacturing methods.

摘要： A magnetic write head for perpendicular magnetic recording. The write head has a secondary flare point defined by magnetic structures that extend from the sides of the write pole, but not over the trailing edge of the write pole. The magnetic structures each have a front edge that defines the secondary flare point. By constructing the magnetic structures so that they only extend from the sides of the write pole and not over the write pole, they can be formed by electroplating, while leafing the mask structure (used to define the write pole) still intact, thereby greatly simplifying manufacture and preventing damage to the write pole during manufacture.

摘要： A magnetic write head for perpendicular magnetic recording that has a write pole and a trailing or side shield that has a leading edge that extends to or beyond the leading edge of write pole, thereby ensuring complete side magnetic shielding. The write head can be formed by forming the write pole on a non-magnetic substrate that is constructed of a material that can be readily removed by reactive ion etching (RIE). The write pole can be formed by depositing a layer of magnetic write pole material over the substrate and then forming a mask over the magnetic write pole material. An ion mill can be performed to define the write pole, and then a reactive ion etch can be performed to notch the substrate, so that when a non-magnetic shield gap material is deposited it will be below or at the bottom of the write pole. Then a magnetic shield material can be deposited to form a shield having a leading edge that extends beyond the leading edge of the write pole.

摘要： A method for manufacturing a magnetic sensor that includes depositing a plurality of mask layers, then forming a stripe height defining mask over the sensor layers. A first ion milling is performed just sufficiently to remove portions of the free layer that are not protected by the stripe height defining mask, the first ion milling being terminated at the non-magnetic barrier or spacer layer. A dielectric layer is then deposited, preferably by ion beam deposition. A second ion milling is then performed to remove portions of the pinned layer structure that are not protected by the mask, the free layer being protected during the second ion milling by the dielectric layer.

摘要： Embodiments herein generally relate to TMR readers and methods for their manufacture. The embodiments discussed herein disclose TMR readers that utilize a structure that avoids use of the DLC layer over the sensor structure and over the hard bias layer. The capping structure over the sensor structure functions as both a protective layer for the sensor structure and a CMP stop layer. The hard bias capping structure functions as both a protective structure for the hard bias layer and as a CMP stop layer. The capping structures that are free of DLC reduce the formation of notches in the second shield layer so that second shield layer is substantially flat.
