    • A thin film piezoelectric element includes a piezoelectric thin film layer, a seed layer and an elastic substrate layer. The piezoelectric thin film layer is a laminated structure comprising a first electrode layer, a second electrode layer and a piezoelectric layer sandwiched between the first electrode layer and the second electrode layer. The seed layer is formed on the second electrode layer, and the elastic substrate layer is formed on the seed layer. The thin film piezoelectric element is a single layer structure and has an elastic substrate layer for supporting the single layer structure, thereby it has enough stiffness and flexibility to afford facilities for manufacture and assembly and to avoid film peeling and deformation, ultimately increasing the production efficiency and lowering the cost. The invention also discloses a method for manufacturing the thin film piezoelectric element, a head gimal assembly and a disk drive unit with the same.

    • A disk drive slider positioner (180) includes a frame (184) having a pair of arms (216a, 216b) that cantilever from a base (188). A slider (140) is positioned within frame (184). A pair of slots (224a, 224b) extend down through the frame (184) and also extend along part of the corresponding arm (216a, 216b). Each slot (224a, 224b) includes a corresponding first slot section (228a, 228b) and a wider corresponding second slot section (232a, 232b). A material (240) that is more pliable than the frame (184) preferably occupies the entire length of each first slot section (228a, 228b). Excess first material (240) may overflow into the corresponding wider second slot section (232a, 232b), thereby reducing the potential for excess first material (240) occupying any portion of the space between a leading edge (144) of the slider (140) and the frame (188).
    • 磁盘驱动器滑块定位器(180)包括具有从基座(188)悬臂的一对臂(216a,216b)的框架(184)。 滑块(140)位于框架(184)内。 一对槽(224a,224b)向下延伸通过框架(184)并且还沿着相应臂(216a,216b)的一部分延伸。 每个槽(224a,224b)包括对应的第一槽部分(228a,228b)和较宽的对应的第二槽部分(232a,232b)。 比框架(184)更柔软的材料(240)优选地占据每个第一槽部分(228a,228b)的整个长度。 过量的第一材料(240)可能溢出到对应的较宽的第二狭槽部分(232a,232b)中,从而减少占据滑块(140)的前缘(144)之间的空间的任何部分的多余的第一材料(240) )和框架(188)。
