    摘要: Adjusting the resonance of a power distribution network in a device to ensure a resonance frequency of the device is outside of a frequency band of wireless signals, other interference signals, or interference signals intrinsic to the device. The resonance frequency may be adjusted by cutting slices into the power and/or ground planes such that a serpentine pattern (or other desired pattern) is formed. The serpentine pattern increases the length that the current travels along the power/ground plane and thus, changes the resonance frequency of the device.

    摘要: Actively controlling ESI voltage on an object such as a magnetic storage disk (12), a rotating MR head, or insulator, includes the method and system for actively monitoring (92) a generated ESI voltage on the object (12). The method and system generate (100, 102, and 104) a signal responsive to the generated ESI voltage. Then, an opposing ESI voltage is produced (76) from the responsive signal. The method and system then apply the opposing ESI voltage (76) to the object (12) for opposing and controlling the generated ESI voltage.

    摘要: In a magnetic read/write transducer, the elements of the magnetoresistive (MR) and inductive heads are shorted together and to the slider substrate to provide a low resistance, conductive path bypassing the MR sensor element and minimizing electrical current through the MR sensor element during discharge of static electric charge. The MR sensor element, the MR conductive leads, the MR magnetic shield elements and inductive pole tips exposed at the slider air bearing surface are shorted together and to the slider substrate by a layer of conductive material, such as tungsten, formed over the slider air bearing surface. The conductive layer shorts the head elements together and to the slider substrate thus protecting the head against ESD/EOS damage during subsequent handling and assembly. The conductive layer is removed by wet etching prior to placing the magnetic head into operation in a magnetic storage system.

    摘要: A disk drive electrical interconnect includes one or more electrical contacts for providing a controlled discharge form a disk drive head in a manner that reduces the potential for damaging the head in preparation for testing or the like. In some embodiments the electrical interconnect includes a charge dissipation electrical contact that is interconnected with a read element of the head using an electrical trace. A resistor is disposed in series between the charge dissipation electrical contact and the read element. A probe may engage the charge dissipation electrical contact to remove the electrical charge from the read element at a desired rate because of the resistor. Once the electrical charge has been sufficiently dissipated, another probe may engage another contact of the electrical interconnect to provide a desired electrical signal to the head.

    摘要: A method and corresponding structure for establishing an electrical interconnection is disclosed. There are at least two conductors in one embodiment. The first conductor is preferably a static dissipative material, while the second conductor may be of any conventional electrically conductive material (e.g., copper). These two conductors move relative to each other. More specifically, the first conductor is brought into contact with a device having a stored charged. After a certain amount of relative movement between the first and second conductors, and while the first conductor has remained in contact with the device to allow for dissipation of at least a portion of the charge therefrom, the second conductor is then brought into contact with the device.
