摘要： The subject matter disclosed herein provides methods for manufacturing an electronic lapping guide and a magnetic read head assembly. The magnetoresistive head assembly includes a sensing element that has a front edge and a front flux guide that has a back edge, such that the sensing element front edge and the front flux guide back edge share a common interface that defines an interface plane normal to the surface of a wafer substrate. The electronic lapping guide comprises a conductive material adapted to attach to two electrical leads for measuring a resistance through the conductive material. The conductive material may include a conductive material back edge aligned with the interface plane. The resistance of the conductive material may be inversely proportional to a conductive material length normal to the interface plane.

摘要： An improved magnetic head for a hard disk drive including a lead overlaid read head in which the read width and read gap are reduced. The read width, which corresponds to the distance between the inner ends of the overlaid electrical leads, is reduced by the fabrication of a thin read width insulation member prior to the fabrication of the overlaid electrical leads. The read gap is reduced by fabricating the overlaid electrical leads from a magnetic, electrically conductive material such as NiFe, whereby the overlaid electrical leads also function as a magnetic shield. The read gap, which is the distance between the first and second magnetic shields is thus reduced as compared to the prior art by the thickness of the electrical leads and the thickness of the prior art second insulation layer formed between the electrical leads and the second magnetic shield.
摘要翻译：一种用于硬盘驱动器的改进磁头，包括读出宽度和读取间隙减小的引线重叠读头。通过在制造覆盖的电引线之前制造薄的读宽度绝缘部件，减小对应于重叠的电引线的内端之间的距离的读宽度。通过从诸如NiFe的磁性导电材料制造覆盖的电引线来减小读取间隙，由此重叠的电引线也用作磁屏蔽。因此，与现有技术相比，通过电引线的厚度和形成在电引线和第二磁屏蔽之间的现有技术的第二绝缘层的厚度相比，第一和第二磁屏蔽之间的距离减小了读取间隙屏蔽。

摘要： A magnetic write head for perpendicular magnetic recording that has a helical coil design that reduces manufacturing complexity and increases cycle time for manufacture. The write head includes a write pole and a helical write coil having upper coil portions that pass above the write pole and lower coil portions that pass below the write pole. The upper and lower coil portions are connected with another by connection studs. Whereas the upper and lower coil portions are constructed of a non-magnetic, electrically conductive material such as Cu, the connection studs are constructed of a magnetic, electrically conductive material such as NiFe. By constructing the connection studs of a magnetic material, they can be constructed in the same manufacturing steps used to manufacture various magnetic structures of the write head, such as a magnetic shaping layer and/or the back gap. This greatly simplifies the manufacture of the write head by eliminating many additional manufacturing steps that would otherwise be required to manufacture a helical coil having non-magnetic connection studs.
摘要翻译：一种用于垂直磁记录的磁头，具有螺旋线圈设计，可降低制造复杂性并增加制造周期。写入头包括写入极和螺旋写入线圈，其具有通过写入磁极之下的上部线圈部分和通过写入极下方的下部线圈部分。上下线圈部分通过连接柱连接。尽管上部和下部线圈部分由诸如Cu的非磁性导电材料构成，但是连接柱由诸如NiFe的磁性导电材料构成。通过构造磁性材料的连接柱，它们可以以用于制造写入头的各种磁性结构的相同的制造步骤，例如磁性成形层和/或后部间隙来构造。这通过消除制造具有非磁性连接柱螺旋线圈的另外制造步骤而大大简化了写入头的制造。

摘要： Test methods and components are disclosed for testing the quality of lift-off processes in wafer fabrication. A wafer is populated with one or more test components along with the functional components. These test components are fabricated with holes in an insulation layer that is deposited between conductive layers, where the holes were created by the same or similar lift-off process that is used to fabricate the functional components on the wafer. The test components may then be measured in order to determine the quality of the holes created by the lift-off process. The quality of the lift-off process used to fabricate the functional components may then be determined based on the quality of the holes in the test components.

摘要： A method for manufacturing a magnetic write head having a write pole with a flared step feature that defines a secondary flare point. The method involves depositing a magnetic write pole material on a substrate and then depositing a magnetic material over the write pole material followed by a non-magnetic material. A first mask is formed having a front edge to define the location of the secondary flare point, and one or more material removal processes are used to remove portions of the magnetic layer and non-magnetic layer that are not protected by this first mask. The first mask is replaced by a second mask that is configured to define a write pole, and an ion milling is performed to define the write pole. Shadowing from the magnetic layer and non-magnetic layer form a flared secondary flare point.
