摘要： When wire-bonding process is effected, a head assembly is held between a pair of clamp members. A head slider is urged against a microactuator. The urging force is transmitted to the microactuator through second adhesive layers. Since the second adhesive layers are positioned symmetrically around the rotational axis of the head slider, the urging force tends to act along the rotational axis. The microactuator is simultaneously urged against the support member. The urging force is transmitted from a first adhesive layer to the support member. Since the first adhesive layer extends around the rotational axis, the urging force tends to act along the rotational axis. The head slider is thus allowed to keep a uniform attitude. The microactuator is also allowed to keep a uniform attitude. The microactuator is prevented from suffering from substantial bending stresses.
摘要翻译：当进行引线接合工艺时，头部组件保持在一对夹紧构件之间。磁头滑块被推向微型致动器。推动力通过第二粘合剂层传递到微致动器。由于第二粘合剂层围绕磁头滑块的旋转轴线对称定位，所以推动力倾向于沿旋转轴线作用。微型致动器同时被推靠在支撑构件上。推动力从第一粘合剂层传递到支撑构件。由于第一粘合剂层围绕旋转轴线延伸，所以推动力倾向于沿着旋转轴线起作用。因此，头部滑块被允许保持均匀的姿态。微型制动器也可以保持统一的态度。防止微致动器遭受实质的弯曲应力。

摘要： A piezoelectric actuator set includes a pair of elongated piezoelectric actuators. The elongated piezoelectric actuators establish the standard attitude of a head slider when no electric signal is supplied to the piezoelectric actuator set. When the electric signal is applied to the piezoelectric actuator set, the tip ends are pulled back toward the base ends in the elongated piezoelectric actuators. The piezoelectric actuator set generates a couple for driving the head slider for rotation around the rotational axis only in a predetermined direction from the standard attitude. The moment of inertia can be reduced in the head slider during rotation as compared with the case where the head slider is moved based on a swinging movement. The natural frequency can be raised in the vibration system comprising the head slider and the piezoelectric actuator set. The frequency of the electric signal or servo signal can be set over a wider frequency range.
