  • Grounding post to reduce EMI noise effects in disc drives
    Patent number: 6388834
    Abstract: An apparatus for reducing transmission of EMI noise effects originating within disc drives by including a grounding member positioned between at least a portion of a flex circuit and an EMI noise source. The grounding member makes electrically conductive contact with the cover and base plate of the disc drive and thereby provides an alternative pathway for EMI noise, as opposed to traveling along the actuator arm (E block). By reducing the transmission of EMI noise, the number of read errors from the disc is likewise minimized.
