摘要： The hard disk testing and certifying device of the present invention includes a spin stand to rotate a disk to be tested. A single read/write head, including both a write head and a read head is mounted upon an armature which movably supports the read/write head. The device includes a computerized control system and signal processing system that provides write signals to the write head and receives and processes read head signals from the read head. In the preferred embodiment the read/write head simultaneously provides write signals to the disk and receives read signals from the disk. Preferably, the read/write head functions continually and the certification testing is conducted utilizing a spiral path. In the preferred read/write head the read head is disposed behind the write head and an electromagnetic field shield is disposed between them to reduce electromagnetic field interference between the write head and the read head during simultaneous operation. The read/write head may also include an electromagnetic field interference element to further reduce signal interference at the read head.

摘要： A method makes an inverted merged MR head with a second pole tip which is self-aligned with a top first pole tip. After forming a bottom first pole tip layer, a top first pole tip is frame plated thereon with a width that defines a track width of the merged MR head. A photoresist layer, which is employed in the frame plating of the top first pole tip, is then soft baked which causes a photoresist opening above the top first pole tip to have sloping side edges which form a recess. An electrically-conductive sacrificial layer, such as copper, is then plated into the recess on top of the top first pole tip and the photoresist is removed. A forming layer, such as alumina, is then deposited and lapped so that the forming layer and the sacrificial layer have top surfaces that are flush with respect to one another. The sacrificial layer is then removed by an etchant that will not attack the materials of the pole tips and the forming layer. The forming layer now has a recess with sloping edges into which a gap layer, a seedlayer and a second pole tip layer are deposited. By this method the second pole tip is self-aligned with the top first pole tip with the second pole tip having a bottom that is substantially the same width as the top of the top first pole tip.
摘要翻译：一种方法使得具有与顶部第一极尖自身对准的第二极尖的反向合并MR头。在形成底部第一极尖端层之后，顶部第一极尖端在其上被框架镀覆，其宽度限定了合并的MR头的轨道宽度。用于顶部第一极尖端的框架电镀中的光致抗蚀剂层然后被软烘烤，这使得顶部第一极尖端上方的光致抗蚀剂开口具有形成凹部的倾斜侧边缘。然后将诸如铜的导电牺牲层电镀到顶部第一极尖顶部的凹部中，并且去除光致抗蚀剂。然后沉积和研磨诸如氧化铝的成形层，使得成形层和牺牲层具有相对于彼此齐平的顶表面。然后通过不会攻击极尖和成形层的材料的蚀刻剂去除牺牲层。成形层现在具有倾斜边缘的凹部，间隙层，籽晶层和第二极尖端层沉积到该凹部中。通过该方法，第二极尖与顶部第一极尖自对准，第二极尖具有与顶部第一极尖的顶部基本相同的宽度的底部。

摘要： An inductive write head has a pole tip region between an air bearing surface (ABS) and a flare point, and a yoke region located between the flare point and a back gap. The write head includes first and second pole piece layers, wherein the second pole piece layer has first and second components. The first component extends from an ABS end, which is located at the ABS, to a recessed end which is located in the yoke region. The second component extends from a recessed end, which is spaced from the ABS, to the back gap. The second component interfaces with the first component in a stitched region so that the first component defines a pole tip in the pole tip region and the second component defines a yoke in the yoke region. A first insulation layer extends from a recessed end, which is spaced from the ABS, into the yoke region. The recessed end of the first insulation layer defines a zero throat height. The first component is sandwiched between the first insulation layer and the second component. The pole tip of the first component can be formed with well-defined side walls during a photoresist step since a flared portion of the second pole piece is located in a planar region of the first insulation layer. With this arrangement, reflective notching into the second pole piece region is avoided. Secondly, a large pedestal formed by the second pole piece provides a large region to stitch the yoke. Due to the large real estate available to stitch the yoke, its forward placement can be recessed from the ABS.

摘要： The present invention employs a ZTH defining insulation layer with a relatively long flat region along with a scheme for eliminating reflective notching from the next insulation layer on top of the ZTH defining insulation layer. This has been accomplished by providing the next insulation layer with a plurality of sloping surfaces which are oriented so that light reflected by the sloping surfaces is directed to areas remote from a pattern of a second pole tip in a photoresist layer which is employed for fabricating the second pole tip. The sloping surfaces terminate at a non-linear front edge which may include a plurality of straight edges extending in predetermined directions. The directions of these straight edges will define the orientations of the sloping surfaces. In one embodiment the straight edges may all be non-parallel and non-perpendicular to the ABS. In another embodiment a first plurality of the straight edges may be perpendicular to the ABS and a second plurality of the straight edges may be at a non-perpendicular angle to the ABS with the first and second plurality of straight edges alternating with respect to one another.
摘要翻译：本发明采用具有相对长的平坦区域的ZTH限定绝缘层以及用于消除来自ZTH限定绝缘层顶部的下一绝缘层的反射缝合的方案。这已经通过为下一个绝缘层提供多个倾斜表面来实现，所述多个倾斜表面被定向成使得由倾斜表面反射的光被引导到远离光致抗蚀剂层中的第二极尖的图案的区域，该光致抗蚀剂层用于制造第二极点。倾斜表面终止于非线性前边缘，其可以包括沿预定方向延伸的多个直边缘。这些直边的方向将限定倾斜表面的取向。在一个实施例中，直边可以全部是不平行的，而非垂直于ABS。在另一个实施例中，第一多个直边缘可以垂直于ABS，并且第二多个直边缘可以与ABS的非垂直的角度，第一和第二多个直边相对于彼此交替。

摘要： A device independent, frequency driven layout system and method for field programmable gate arrays ("FPGA") which allow for a circuit designer to specify the desired operating frequencies of clock signals in a given design to the automatic layout system to generate, if possible, a physical FPGA layout which will allow the targeted FPGA device to operate at the specified frequencies. Actual net, path and skew requirements are automatically generated and fed to the place and route tools. The system and method of the present invention evaluates the frequency constraints, determines what delay ranges are acceptable for each electrical connection and targets those ranges throughout the layout.

摘要： A ducted separator in a compressor-based cooling assembly is connected to an oil/gas outlet of the compressor. The ducted separator is a pipe with at least one bend in it which collects oil in a manner which can achieve 98% oil carry over efficiency. The ducted separator may optionally be connected to a second phase separator such as a centrifugal cylinder. In that case, the height of the centrifugal cylinder can be significantly reduced compared with conventional arrangements. Alternatively, a simpler impingement surface such as one or more baffles may be used as the second phase separator or just a collection chamber.
