  • Flex on suspension with dissipative polymer substrate acting as bleed resistor for minimizing ESD damage
    Patent number: 6927951
    Abstract: A head gimbal assembly that includes a bleed resistor applied over a specified area of the reader, writer and ground leads in order to protect from ESD damage is disclosed. The present invention address the need for an ESD protection system that includes a consistent and secure connection with leads, that does not contaminate the drive environment and applies a consistent resistivity to both the reader and writer element by providing a head gimbal assembly with strategically placed bleed resistors that will protect the read element from transient charge produced any time during the fabrication, assembly, testing and shipment of the disc drive.
    Type: Grant
    Filed: April 2, 2002
    Date of Patent: August 9, 2005
