    摘要： A novel thin film magnetic head fabrication process is provided for fabricating a plurality of thin film magnetic head elements. The process begins with the selection of an appropriate wafer substrate of suitable size and quality. At least two primary sub-areas of the wafer substrate are designated as work areas for the deposition of magnetic recording transducer elements. The work areas have first and second end portions and are arranged in mutually adjacent relation along a shared boundary zone that extends in a first direction through the wafer substrate between the first and second end portions. The wafer substrate is populated with plural rows of magnetic recording transducer elements in the designated work areas such that the plural rows extend in a second direction that is substantially perpendicular to the first direction. The work areas are separated from the wafer substrate and magnetic transducer slider elements are fabricated from the plural rows of magnetic recording transducer elements. The process steps are such that they reduce the number of fabrication steps to a minimum while increasing the consistency of throat and stripe heights.

    摘要： An integrated read/write head assembly incorporates a thin film inductive write head subassembly comprising first and second pole pieces that define a write transducing gap, and a magnetoresistive read subassembly disposed in the write gap. The first write pole piece is extended so as to provide a planar conductive path from the terminal connections or studs to the magnetoresistive read subassembly, thereby forming a uniform surface for deposition of the magnetoresistive read subassembly.

    摘要： An electrical lapping guide resistor for measuring the lapping distance in a process for manufacturing thin film magnetic transducers. Final throat height is measured with an electrical lapping guide resistor which provides a linear change in resistance versus lapping distance. The lapping guide resistor is configured in a shape such that the effective length of the resistors increases as the effective width decreases. In a preferred embodiment of the invention, the resistor includes first and second converging edges which extend from a rearward edge parallel to the final throat height toward the lapping surface. Conductors are disposed along the converging edges. Measurements of the change in lapping distance are effected by measuring the distance between the conductors.

    摘要： A method for making a thin film magnetic head assembly comprising the steps of depositing a first magnetic pole piece layer, depositing a nonmagnetic material gap forming layer, and depositing a protective layer of etch resistant material. A layer of insulation is deposited upon which is formed a conductive coil. A leveling pad of insulation is deposited over the conductive coil, and the part of the protective layer which is not covered by the insulation is removed. The gap forming layer is therefore protected during the processing steps so that a desired gap length is produced. The second magnetic pole piece layer is then deposited to complete the magnetic circuit.

    摘要： A dual element electrical lapping guide system is disclosed for a row of multi-layer dual element magnetoresistive and inductive magnetic transducers formed on a substrate, which will be used to form sliders, the sliders being separated by separation kerfs, and the multi-layer transducers aligned along an edge of the substrate for lapping of the edge. The dual element lapping guide system comprises superposed resistive elements and electrical switch elements, each positioned in one of the separation kerfs, and having an edge thereof positioned so as to be aligned with the edge of the row and subject to lapping of the row. Each electrical switch element comprises a bottom and a top layer connected at one end thereof and separated at the other end thereof by an insulation layer, so as to be initially closed at the connected end, which end is aligned with the edge of the multi-layer transducers and subject to lapping of the row at the connected end to open the switch element.
