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.
摘要翻译：用于垂直磁记录的磁写头。写头具有由磁性结构限定的次级耀斑，其从写入极的侧面延伸，但不在写入极的后缘上方。磁性结构各自具有限定次级耀斑点的前边缘。通过构造磁结构，使得它们仅从写入极的侧面延伸而不是在写入极之上，它们可以通过电镀形成，同时使掩模结构（用于定义写入极）仍然完整，从而大大简化在制造过程中制造和防止对写入极的损坏。

摘要： A studded trailing shield design and method for manufacture thereof. The studded trailing shield design maintains critical spacing between the trailing shield and the write pole and also maintains critical spacing between the studded, trailing shield connecting structure, even in a head design having read and write elements that are not aligned with one another.

摘要： Described are a device and system to transmit data to or receive data from one or more data lane interfaces. Each data lane interface may be capable of transmitting a serial data signal to or receiving a serial data signal from a data lane in a device-to-device interconnection. An effective data rate may be varied based, at least in part, upon a number of the data lane interfaces actively transmitting a serial data signal to or receiving a serial data signal from the device-to-device interconnection.

摘要： Heads for perpendicular recording using a floating-trailing shield are described. The floating-trailing shield is separated from the main pole piece by a layer of non-magnetic material along its entire length and the air bearing surface of the floating-trailing shield is substantially larger than that of the main pole piece. The reluctance between the trailing shield and the underlayer in the recording medium is made so low that both are at the same magnetomotive force (or potential), so that no direct connection is needed between the floating-trailing shield and the yoke. When the head is used in a storage system with a magnetic recording medium with a soft underlayer, the floating-trailing shield is, in effect, magnetically shorted to the return pole piece during recording. In one embodiment the floating-trailing shield wraps around the sides of the main pole piece.
摘要翻译：描述使用浮动后挡板进行垂直记录的头部。浮动后挡板沿着其整个长度由非磁性材料层与主极片分开，并且浮动后挡板的空气支承表面基本上大于主极片的空气支承表面。记录介质中的后屏蔽和底层之间的磁阻被制作得很低以致两者都具有相同的磁动势（或电位），使得在浮动后挡板和轭之间不需要直接连接。当头部用于具有软底层的磁记录介质的存储系统中时，浮动拖尾屏蔽件实际上在记录期间与返回极片磁性短路。在一个实施例中，浮动后挡板围绕主极片的侧面包裹。

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： A method for fabricating a coil and pedestal for a write head using a common seed layer is described. A nonmetallic gap layer is deposited on a planarized pole piece surface. Openings for the pole piece pedestal and the back gap pole piece are etched through the nonmetallic gap layer. A seed layer comprising a magnetic material is deposited on the etched gap layer. Preferably the coil is fabricated first on the planar surface of the seed layer. The coil structure, the pedestal pole piece, back-gap pole piece, side and center tap connections are fabricated on the same seed layer. The remaining seed layer is removed, the coil is encapsulated, the wafer is refilled with alumina and the wafer is planarized. The prior art process can be resumed at this point. Optionally a second seed layer such as copper (Cu) can be used.

摘要： Methods suitable for use in making a write coil of a magnetic head includes the steps of forming a seed layer made of ruthenium (Ru) over a substrate; forming, over the seed layer, a patterned resist having a plurality of write coil trenches patterned therein; electroplating electrically conductive materials within the plurality of write coil trenches to thereby form a plurality of write coil layers; removing the patterned resist; and performing a reactive ion etch (RIE) in ozone gas (O3) for removing exposed seed layer materials in between the plurality of write coil layers. Advantageously, the write coil layers remain undamaged from the RIE in the ozone gas. Other structures may be fabricated in a similar manner.

摘要： A method for manufacturing a write head having a small write pole tip that emits magnetic flux sufficient for effective perpendicular recording. The method creates a leading edge taper (LET) between the write pole tip and a magnetic flux guide to create a sufficient magnetic flux in the write pole. The LET is fabricated by ion milling away a sacrificial striated material whose layers have different rates of ion milling. The top layer of material thus mills away faster than lower layers, creating the required tapering of a negative mold. An endpoint material stops the milling. The LET magnetic material is then spattered into the negative mold, resulting in a well defined taper of magnetic flux shaping material extending the magnetic flux guide to the write pole tip, such that the write pole tip is able to emit sufficient magnetic flux for perpendicular recording.
摘要翻译：一种用于制造写头的方法，所述写头具有发射足以有效垂直记录的磁通量的小写尖端。该方法在写极尖和磁通引导之间产生前缘锥形（LET），以在写入极中产生足够的磁通量。 LET通过离子铣削除去具有不同离子铣削速率的牺牲条纹材料来制造。因此，顶层材料的磨料速度比较低，从而产生了负模具所需的锥形化。端点材料停止铣削。然后将LET磁性材料溅入阴模中，产生明确限定的磁通量成形材料的锥形，该磁通量成形材料将磁通引导件延伸到写入磁极尖端，使得写入磁极尖端能够发射足够的磁通量用于垂直记录。

摘要： An apparatus for patterning a self-aligned coil using a damascene process is disclosed. Coil pockets are formed in a first insulation layer disposed over a first pole layer. A barrier/seed layer is deposited along walls of the coil pockets in the insulation layer. Copper is formed in the coil pockets and over the insulation layer. The copper is planarized down to the insulation layer. The self-aligned coil process packs more copper into the same coil pocket and relaxes the coil alignment tolerance. Protrusions are prevented because of the more efficient and uniform spacing of the coil to reduce heat buildup in the head during a write.
摘要翻译：公开了一种使用镶嵌工艺图案化自对准线圈的装置。在设置在第一极层上的第一绝缘层中形成线圈腔。隔离层/籽晶层沿绝缘层中的线圈袋的壁被沉积。在线圈袋中形成铜，并在绝缘层上形成铜。铜平坦化到绝缘层。自对准线圈工艺将更多的铜包装到相同的线圈袋中，并松弛线圈对准公差。由于在写入期间线圈的间隔更加有效和均匀以减少头部的积聚，所以防止了突起。

摘要： An embodiment of the invention is a head for perpendicular recording that has a trailing shield and side shields that are connected to the return pole piece by two studs of ferromagnetic material. The studs extend parallel to the track direction and are located a sufficient distance away from the main pole piece to reduce the flux flow from the main pole piece to the studs. Optionally the studs can be recessed behind the air-bearing surface. The preferred embodiment of the invention is a magnetic transducer with separated read and write heads for perpendicular recording.
