  • Patent number: 10366713
    Abstract: A pad/trace line layout for a PMR writer structure having two or more writers on a slider, and a process for selecting the best of the multiple writers is disclosed. Each writer is individually probed with a spin stand test device to generate performance results including bit error rate (BER), and area density capability (ADC). After the best writer is determined, the slider is integrated in a HGA. Only the best writer is connected through trace lines to a preamp to enable functionality. At least one trace line has a plurality of arms that enable flexibility in connecting the best writer to the preamp while other arms are not connected. In some embodiments, all writers share a common W? pad that is connected to the preamp through one of two trace lines while the other trace line has one of the plurality of arms connected to the best writer.

  • Publication number: 20190085152
    Abstract: An interlayer comprised of a thermoplastic resin, varying amounts of an epoxidized vegetable oil, and, optionally, a conventional plasticizer. The use of a thermoplastic resin, an epoxidized vegetable (plant) oil, and, optionally, a conventional plasticizer creates synergy allowing the flow of the interlayer to be increased without sacrificing other characteristics typically associated with an increased flow (e.g., increased blocking and creep, exudation, surface roughness formation, decreased mechanical strength, and decreased manufacturing capability). In this regard, the epoxidized vegetable oil acts as a flow improvement agent, resulting in a high-flow interlayer. As a result, a thinner interlayer can be utilized in forming multiple layer panels because the resulting thinner interlayer has improved flow properties.
