  • Publication number: 20070139853
    Abstract: A cable having an electrostatic discharge (ESD) dissipative coating according to one embodiment includes an elongate lead; and an ESD dissipative coating functioning as an electrical insulator for the lead, wherein no other insulator excluding an optional adhesive is present on the cable. A cable having an ESD dissipative coating according to another embodiment includes at least 16 leads, and an ESD dissipative coating operatively coupled to the leads. A cable having an ESD dissipative coating according to yet another embodiment includes an elongate lead having a length defined therealong between distal ends thereof; and an ESD dissipative coating operatively coupled to the lead and extending along a majority of the length of the lead, wherein the ESD dissipative coating has an ESD dissipative surface resistance of from about 1×106 to about 1×108 ohm/sq.

  • Publication number: 20060023382
    Abstract: A cable having an electrostatic discharge (ESD) dissipative coating. The cable includes a lead and an ESD dissipative coating operatively coupled to the lead. Other layers such as adhesives and insulating layers can be provided. The ESD dissipative coating can also function as the insulator for the lead.

  • Patent number: 6069773
    Abstract: A uniquely configured flexure tongue of a head/gimbal assembly (HGA) provides for parallel positioning of a slider air bearing surface (ABS) during merge and a limitation of pitch of the slider during non-merge. A cantilevered end of the flexure tongue is provided with a finger extension which can be employed for merge operations and a remainder cantilevered end portion adjacent a base of the finger can be employed for limiting pitch of the slider. When a merge comb engages multiple flexure fingers of multiple suspensions in a head stack assembly the air bearing surfaces of the sliders are positioned parallel with respect to one another. This allows maximum disk stack density when a head stack assembly is merged with a head stack assembly. The flexure finger allows various arrangements to be employed for implementing a merge. The present invention also cooperates with a prior art roll limiter so that during merge a three point fixation normalizes a slider at zero pitch.
