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.

摘要： Methods of recording head fabrication are provided to fabricate a region of separation material between a write pole and a shield of a write head that forms a controlled spacing between the write pole and the shield of the write head. The method comprises forming a mask structure having an opening exposing a write pole of the write head and forming separation material above the portions of the write pole exposed by the opening. The method further comprises removing the mask structure and forming a shield of the write head above the separation material. The separation material forms a spacing between the write pole and the shield, which controls the amount of flux from the write pole absorbed by a shield (e.g., a wrap around shield) of the write head.

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 write element for use in perpendicular magnetic recording. The write element including a write pole and a self aligned wrap around shield that can have a trailing shield gap thickness that is different from its side shield gap thickness. The materials making up the trailing shield gap and the side shield gaps can be different materials or can be the same material deposited in two different steps. The side or wrap around portions of the trailing shield can extend down to the level of the leading edge of the write pole or can terminate at some point between the levels of the leading and trailing edge to form a partial wrap around trailing shield.

摘要： A magnetic head for use in a perpendicular recording system having a novel shield structure that provides exceptional magnetic shielding from extraneous magnetic fields such as from a write coil, shaping layer or return pole of the write head. The magnetic head includes a write pole, a return pole and a magnetic shield that is magnetically connected with the return pole near the ABS and extends toward the write pole. The shield is formed with a notch at its edge closest to the write pole. The notch assures adequate physical, magnetic, and electrical separation between the write pole and the shield, while allowing un-notched portions of the shield to provide additional magnetic shielding.

摘要： A contact magnetic transfer (CMT) master template has a flexible plastic film with a planarized top or upper surface containing magnetic islands separated from one another by nonmagnetic regions. The flexible plastic film is secured at its perimeter to a silicon annulus that provides rigid support at the perimeter of the film. The plastic film is preferably polyimide that has recesses filled with the magnetic material that form the pattern of magnetic islands. The upper surfaces of the islands and the upper surfaces of the nonmagnetic regions form a continuous planar surface. The nonmagnetic regions are formed of chemical-mechanical-polishing (CMP) stop layer material that remains after a CMP process has planarized the upper surface of the plastic film.

摘要： A perpendicular magnetic recording write head has a flux conductor in contact with the write pole. The flux conductor is substantially wider than the write pole tip in the cross-track direction and has a blunt end that is recessed from the pole tip end. The region of the flux conductor where its blunt end is in contact with the pole tip is the “choke” point for the write pole, i.e., the point where the flux density is highest. The flux conductor enables the write pole to be made with no flare, or with a flare angle and throat height with a much wider tolerance, which substantially simplifies the manufacturing process. The write head may have a trailing shield and side shields that substantially surround the write pole tip and remove stray fields that may be produced by the flux conductor, so that regions of the recording layer other than the track being written are not adversely affected.
摘要翻译：垂直磁记录写头具有与写极接触的磁通导体。磁通导体在横向磁道方向上基本上比写入磁极尖端更宽，并且具有从磁极末端凹进的钝端。其钝端与极尖接触的磁通导体的区域是写极的“扼流”点，即磁通密度最高的点。磁通导体使写磁极能够制成没有耀斑，或具有更宽公差的喇叭角和喉部高度，这大大简化了制造过程。写头可以具有基本上围绕写磁极尖端的后屏蔽和侧屏蔽，并且去除可能由磁通导体产生的杂散场，使得除了正在写入的磁道之外的记录层的区域不受不利影响。

摘要： Methods and structures for electroplating shield structures for perpendicular thin film write poles having ultra thin non-magnetic top gaps on the order of a few nanometers are disclosed. Ultra thin, conductive seed layers serve a dual purpose as both plating seed layer and non-magnetic top gap for the write pole. Due to reduced current carrying capacity of ultra thin seed layers, an additional thick seed layer is also employed to aid delivering plating current to regions near the pole.

摘要： A method for manufacturing a write pole for perpendicular magnetic recording for accurately defining a side shield throat height and write pole flare point. The method includes the formation of a magnetic structure that provides an electronic lapping guide as well as providing the structure for both the side shields and the write pole. The magnetic structure includes a write pole portion and first and second side shield portions. The side shields portions are magnetically connected with the write pole portion in a region in front of an intended air hearing surface plane (e.g. in the direction from which lapping will progress). The side shields portions are each separated from the write pole portion in a region behind the intended air bearing surface plane by notches that terminate at a desired location relative to the intended air bearing surface plane and which open up in a region behind the intended air bearing surface plane.

摘要： A method of manufacturing a magnetic write head for perpendicular magnetic recording. The method includes the formation of a write pole over a substrate. A non-magnetic side gap layer is deposited and an ion milling is used to remove a portion of the substrate to lower the floor of the substrate. A sacrificial fill layer can then be deposited. A chemical mechanical polishing process can be used to remove the mask structure remaining as a remnant of the formation of the write pole, and then the sacrificial fill layer can be removed. A non-magnetic, electrically conductive material can be deposited to form a tailing gap, an a magnetic material can then be deposited to form a wrap around trailing shield.
