摘要： A magnetic head for a hard disk drive. The magnetic poles of the head are formed with a NiFe alloy having a graduated composition in which a higher Fe concentration is fabricated proximate the write gap layer between the magnetic poles. Each magnetic pole is fabricated in a single electroplating step in which the duty cycle of the electroplating current is altered during the electroplating operation. Where the duty cycle is greatest the Fe ion concentration is likewise greatest.

摘要： The high resistance lead layers of a read head extend straight back into the head from each of the first and second edges of the read sensor. This lessens the length of each of the high resistance lead layers so that they do not have to be made thicker to satisfy resistance requirements. Accordingly, a lateral width of each high resistance lead portion along the ABS and a thickness thereof are chosen so as to minimize the thickness while yet satisfying the resistance requirements. Further, a method of making the first and second lead layers is provided that minimizes the thickness of the high resistance lead layers. Instead of constructing the high resistance lead layers first, the present method constructs the high resistance lead layers last so that the high resistance lead layers are not altered by subsequent processing steps.
摘要翻译：读头的高电阻引线层从读取传感器的第一和第二边缘的每一个直接返回到头部。这降低了每个高电阻引线层的长度，使得它们不必被制成更厚以满足电阻要求。因此，选择沿着ABS的每个高电阻引线部分的横向宽度及其厚度，以便在满足电阻要求的同时使厚度最小化。此外，提供了制造第一和第二引线层的方法，其使得高电阻引线层的厚度最小化。首先，代替构造高电阻引线层，本方法构造最后的高电阻引线层，使得高电阻引线层不会随后的处理步骤而改变。

摘要： A media rework tool includes a gripper assembly having a plurality of opposing arms for grasping predetermined discs within a disc pack. The gripper assembly raises the predetermined discs and any intermediate spacer rings upward for temporary storage on a media guide to allow the remainder of the disc pack to be reworked, such as for replacement of a defective disc or spindle motor. A method of reworking a disc pack includes centering the disc pack between opposing arms of a gripper assembly and beneath a cylindrical media guide. A plurality of the opposing arms close to grasp a predetermined number of discs, and the gripper assembly is raised to transfer the grasped discs, and any intermediate spacer rings, from the spindle motor to the media guide. Following reworking of the remainder of the disc pack, the spindle motor is returned to its centered position relative to the media guide and the gripper assembly. The gripper assembly is then lowered to restack the discs and spacer rings on the spindle motor and the opposing arms are opened to release the discs.

摘要： A fabrication process for a complex magnetic head having a reproducing MR head and a recording ID head comprises the steps of forming the MR head, forming an insulator film on the MR head, forming a photoresist frame on the insulator film, forming a top magnetic pole inside the photoresist frame by plating, trimming the top magnetic pole for defining the end width of the ID head while leaving the photoresist frame, and removing the photoresist frame. The photoresist frame protects the underlying films against the trimming and also protects the top magnetic pole film against an etching solution.

摘要： A method is provided for resetting the magnetization of the pinned and hard biasing layers of a spin valve read head at the row level. In a first embodiment of the invention a first magnetic field is applied substantially perpendicular to the air bearing surface (ABS) at room temperature for setting the magnetic moment of the pinned layer substantially perpendicular to the ABS followed by applying a second magnetic field substantially parallel to the ABS for setting the magnetic moments of the hard biasing layers substantially parallel to the ABS. In a second embodiment of the invention the antiferromagnetic pinning layer is also reset. This is done by heating the pinning layer with a current pulse conducted through the leads to the conductive layers of the spin valve head so that localized heating takes place adjacent the pinning layer as contrasted to ambient heating of the spin valve head. Simultaneous with the localized heating the first magnetic field is applied for orienting the magnetic spins of the pinning layer perpendicular to the ABS and resetting the magnetic moment of the pinned layer perpendicular to the ABS in a single domain state. Subsequently, a second magnetic field is applied for resetting the magnetic moment of the hard biasing layer parallel to the ABS in a single domain state.

摘要： A soft adjacent layer (SAL) magnetoresistive (MR) sensor element and a method for fabricating the soft adjacent layer (SAL) magnetoresistive (MR) sensor element. To practice the method, there is first provided a substrate. There is then formed over the substrate a soft adjacent layer (SAL). There is then formed upon the soft adjacent layer (SAL) a dielectric layer. There is then formed at least in part contacting the dielectric layer a magnetoresistive (MR) layer, where the soft adjacent layer (SAL) and the dielectric layer are planar. The method contemplates the soft adjacent layer (SAL) magnetoresistive (MR) sensor element formed through the method.

摘要： A method is described for making a merged thin film read/write head where a common layer serves as both a magnetic shield for the magentoresistive read element and the first pole piece for the inductive write element, and where the first pole piece thus includes a pedestal pole tip portion that extends up from the first pole piece layer. During fabrication a nonmagnetic spacer layer is deposited over the second pole tip and the gap layer, and then reactive ion etching (RIE) removes the spacer layer from the top of the second pole tip and the gap layer not beneath the second pole piece, but leaves the spacer layer on the sidewalls of the second pole tip. The ion bombardment of the RIE process is perpendicular to the gap layer and is continued after removal of the spacer layer to also remove the gap layer in the region not beneath the second pole piece so that the first pole piece layer is exposed. The RIE uses a gas that is more reactive with the gap material than the material of the second pole tip so that the top surface of the second pole tip is not substantially removed during etching of the gap layer. Next, ion milling removes the material from the layer of the first pole piece to form a first pedestal pole tip beneath the gap. Material ejected from the first pole piece layer during ion milling that gets redeposited on the second pole piece is prevented from contacting the sidewalls of the second pole tip because of the spacer layer.
摘要翻译：描述了一种用于制造合并的薄膜读/写头的方法，其中公共层用作磁阻读取元件的磁屏蔽和用于感应写元件的第一极片，并且其中第一极片因此包括基座极尖部分，其从第一极片层向上延伸。在制造期间，在第二极尖和间隙层上沉积非磁性间隔层，然后反应离子蚀刻（RIE）从第二极尖顶部和第二极片下面的间隙层去除间隔层，但是将间隔层留在第二极尖的侧壁上。 RIE工艺的离子轰击垂直于间隙层，并且在去除间隔层之后继续移除在第二极靴下方的区域中的间隙层，以使第一极片层露出。 RIE使用比间隙材料更能反应的气体，而不是第二极尖的材料，使得在蚀刻间隙层期间第二极尖的顶表面基本上不被去除。接下来，离子铣削从第一极靴的层移除材料以在间隙下方形成第一基座极尖。由于间隔层，防止了离子研磨期间从第一极片层排出的材料再次沉积在第二极片上与第二极尖端的侧壁接触。

摘要： A method of manufacturing a magnetic head by bonding a pair of magnetic cores to each other, wherein a residual stress in the magnetic cores upon bonding them together is controlled so that a permeability of the magnetic cores in the vicinity of a magnetic recording medium sliding surface of the magnetic cores may become maximum. Accordingly, the residual stress in the magnetic cores is controlled so that the permeability of the magnetic cores may surely become maximum after forming the magnetic head, thereby ensuring a superior reproduction efficiency of the magnetic head.

摘要： A method of lapping the air bearing surface of a magnetoresistive head which minimizes the likelihood of interelement shorts at the air bearing surface is described. In a final, linear lapping phase, the air bearing surface is lapped back and forth parallel to the longitudinal axis of the head elements in an oscillatory path across a stationary lapping surface. Any scratches or smears of the elements will be along the length of the elements rather than transverse to the elements. Any transverse scratches or smears occurring in earlier lapping phases will be removed during the linear lapping phase.
