摘要： A magnetic head assembly includes: a slider; an actuator disposed on an end face of the slider; and a magnetic head unit connected to the actuator. The actuator has a structure in which multiple electrodes are arranged in a piezoelectric body, and is driven in d33 mode. In other words, when a predetermined voltage is applied to the actuator, a portion between the electrodes in the piezoelectric body expands or contracts with respect to a voltage application direction. When the piezoelectric body of the actuator expands or contracts, the magnetic head unit is deformed, and the deformation causes a change of the distance between a magnetic head (recording element and reproducing element) and a magnetic recording medium.

摘要： A microscale driving unit includes first and second elongated piezoelectric actuators extending in antiparallel directions. The base ends of the actuators are fixed to a support member. The tip ends of the actuators are fixed to a driven member. First and second electrically conductive members connect the base end of the first or second elongated piezoelectric actuator to the tip end of the second or first elongated piezoelectric actuator. The microscale driving unit allows utilization of a common single wiring pattern connected to both the base end of the first elongated piezoelectric actuator and the tip end of the second elongated piezoelectric actuator when a driving current is supplied to the first and second elongated piezoelectric actuators. Only a smaller area should be required to locate the wiring pattern. A sufficient planar space can be obtained on the surface of the support member.

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 head assembly includes a suspension having a gimbal, a flexible printed wiring sheet having a plurality of conductor patterns and adhered to the suspension, first and second piezoelectric actuators mounted on the gimbal, and a head slider mounted on the first and second piezoelectric actuators. The first and second piezoelectric actuators are adhered to the gimbal at end portion adhesion portions symmetrical with respect to the center of pivotal motion thereof and are adhered to the head slider at end portion adhesion portions on the opposite side disposed symmetrically with respect to the center of pivotal motion similarly. Consequently, when a voltage is applied to the first and second piezoelectric actuators through the flexible printed wiring sheet, a couple of forces can be generated which vary the posture of the head slider only in one direction around the center of pivotal motion.
