    • A head gimbal assembly includes a rotary fine actuator attached to the head mounting tongue. The rotary fine actuator includes a fixed portion, a head mounting platform, first and second piezoelectric elements, and first and second curved compliant members. The first piezoelectric element is bonded to the fixed portion at a first bonding surface, and to the head mounting platform at a second bonding surface. The second piezoelectric element extends between the fixed portion and the head mounting platform. The first and second curved compliant members extend between the fixed portion and the head mounting platform. A read head is bonded to a mounting surface of the head mounting platform. The first and second bonding surfaces are parallel to the mounting surface. The read head is disposed between the first and second piezoelectric elements.
    • 头万向架组件包括附接到头部安装舌头的旋转精细致动器。 旋转精细致动器包括固定部分,头部安装平台,第一和第二压电元件以及第一和第二弯曲柔顺构件。 第一压电元件在第一接合表面处接合到固定部分,并且在第二接合表面处接合到头部安装平台。 第二压电元件在固定部分和头部安装平台之间延伸。 第一和第二弯曲柔性构件在固定部分和头部安装平台之间延伸。 读头与头安装平台的安装面接合。 第一和第二接合表面平行于安装表面。 读头设置在第一和第二压电元件之间。
