  • Patent number: 5333085
    Abstract: A read/write head gimbal is provided including a tab or extension on the end of the gimbal portion which is attached to the head/slider assembly, forming this tab such that, when the gimbal is assembled to the load beam, the formed tab passes through an opening created for this purpose in the load beam, and extends beyond the opening far enough to prevent its returning through the opening after the gimbal and load beam are spot welded together. The tab and opening in the load beam are dimensioned so that during normal read/write operations, there is no contact between the tab and the sides of the opening in the load beam. The tab/opening arrangement is such that shock forces in the direction of travel away from the load beam, or in parallel with the surface of the load beam bracing the gimbal, will result in contact between the tab and the sides of the opening in the load beam, thus preventing excessive motion of the gimbal which could result in permanent deformation of the gimbal.
