摘要： A lift tab for a load/unload type of data storage hard drive and a method of smoothing the lift tab. The method includes the step of striking the lift tab with short duration (e.g. 10-500 nanosecond) energy pulses to melt a thin surface layer of the lift tab. The melted layer flows under surface tension forces, smoothing out bumps and scratches. The melted layer quickly refreezes, forming an exceptionally smooth melted and refrozen spot. Preferably, the melted and refrozen spot is 0.2-10 microns deep. More preferably, the melted and refrozen spot is in the range of 1.0 to 3.0 microns thick. The lift tab can have a large number of melted and refrozen spots. The size of the melted and refrozen spots is practically limited by power available from energy sources such as lasers. Preferably, the melted and refrozen spots are at least several tens of microns in diameter. The present invention includes lift tabs having melted and refrozen spots. Also, the present invention includes head gimbal assemblies and hard drives having lift tabs with melted and refrozen spots.
摘要翻译：用于加载/卸载类型的数据存储硬盘驱动器的升降卡和一个平滑升降卡的方法。该方法包括以短持续时间（例如10-500纳秒）的能量脉冲击打提升翼片以熔化提升翼片的薄表面层的步骤。熔融层在表面张力下流动，平滑突起和划痕。熔融层迅速重新熔化，形成了非常光滑的熔化和冷却点。优选地，熔融和重新冷冻的斑点为0.2-10微米深。更优选地，熔融和重新熔化的斑点在1.0至3.0微米厚的范围内。电梯标签可以有大量熔化和重新焊接的点。熔化和重新熔化的斑点的大小实际上受到诸如激光等能量的能量的限制。优选地，熔融和再次冷冻的斑点直径至少几十微米。本发明包括具有熔融和重新冷冻点的升降片。此外，本发明还包括头部万向节组件和具有熔融和重新冷冻点的升降片的硬盘驱动器。
