Patent number: 8837090Abstract: A head suspension for a disk drive with a load beam having continuous rails and a distal lift tab. A dimple is positioned proximal to the lift tab, either on the load beam or the gimbal, the dimple providing a pitch axis and a roll axis for the slider. The suspension also includes at least one tab member fixed in relation to the load beam, where each of the at least one tab member is aligned with or is distal to the dimple. The at least one tab and a portion of the gimbal define a gimbal limiter that is aligned with or distal to the dimple. The at least one tab member extends either longitudinally or laterally from the load beam at or distal to the dimple.Type: GrantFiled: July 26, 2013Date of Patent: September 16, 2014Assignee: Seagate Technology LLCInventors: Michael Allen Greminger, Razman Zambri, Jackson William Brandts
