摘要： A ramp wherein the amount of deformation in the front end edges of guiding parts caused by thermal expansion. The ramp includes at least two guiding parts individually formed for each suspension arm and made of a polymeric material having a small friction coefficient for guiding the suspension arm by sliding into a accommodation zone, and a guide supporting member made of a material having a thermal expansion coefficient smaller than that of the polymeric material of the guiding part for supporting each guiding part at a predetermined position. The guide supporting member has guide support holes which are located in zones to be contacted with the associated guiding parts, are not contacted with associated recording disks, and are engaged with the associated guiding parts at such positions that distances to the front end edges of the guiding parts become shortest. Each of the guiding parts has a projection. When the projection is engaged in the associated guide support hole, the guiding part guides the suspension arm at a suitable position.

摘要： The present invention prevents a head/slider assembly fixed on a flexure of a head suspension assembly from having an undesired pitching motion when an unexpected excess shock is applied to a hard disk device when the head suspension is at the best position of the unload ramp. A disk drive device in accordance with the present invention comprises: a rotating data recording disk; a head suspension assembly containing a front portion and a rear portion, with the front portion being provided with a tab; a device coupled to the rear portion of the head suspension assembly to move the front portion between an inner most position and an outer most position along a radial direction of the rotating data recording disk; a ramp element containing a support surface for engaging with the tab of the front portion of the head suspension assembly when the front portion is moved to the outer most position; and a flexure mounted on said front portion of the head suspension assembly, and having a front portion disposed towards the tab of the head suspension assembly and a rear portion disposed towards the rear portion of the head suspension assembly.
摘要翻译：本发明防止当磁头悬架处于卸载斜坡的最佳位置时，当硬盘装置发生意外的过度冲击时，固定在磁头悬架组件的挠曲件上的磁头/滑块组件不会产生不期望的俯仰运动。根据本发明的磁盘驱动装置包括：旋转数据记录盘; 头部悬挂组件，其包含前部和后部，前部设有突片; 耦合到所述头部悬挂组件的后部的装置，用于沿着所述旋转数据记录盘的径向移动所述前部在最内侧位置和最外侧位置之间; 斜坡元件，其包含支撑表面，用于当前部移动到最外部位置时与头部悬挂组件的前部的突出部接合; 以及安装在头部悬挂组件的所述前部上的挠曲件，并且具有朝向头部悬挂组件的突出部设置的前部，以及朝向头部悬挂组件的后部设置的后部。
