  • Protective layer on gimbal for scratch mitigation
    Patent number: 8493689
    Abstract: A head gimbal assembly includes a gimbal, a slider, and a polymer layer. The gimbal comprises a metal layer, and the metal layer of the gimbal defines a gimbal mounting portion for attachment to a metallic load beam and a gimbal tongue extending from the gimbal mounting portion. The slider comprises a ceramic material for carrying a transducing head, and at least a portion of the slider is secured to the gimbal tongue. The polymer layer is positioned adjacent to the gimbal and configured for limiting ceramic-to-metal and metal-to-metal contact.
