摘要： A magnetic head actuator provided with a finely movable tracking device having a piezoelectric element is provided for easy wiring to the piezoelectric element and reducing problems such as wire breakage and continuity defects. In the magnetic head actuator, a portion of an FPC board resin base is removed to expose a portion of the feeding line that extends onto a voltage impressing electrode. An electrical and mechanical connection is made between the electrode and the exposed portion of the feeding line by ultrasonic bonding, Au ball bonding, or stud bumping.

摘要： A method for mounting a flexible flexure, which has a slider fixed thereto and having an electro-magnetic conversion element integrally, on a load beam includes the steps of joining a main flexure, which has a junction piece for joining the load beam, to the load beam with the junction piece therebetween; inspecting characteristics by floating the electromagnetic conversion element onto a magnetic disc; when the characteristics do not satisfy a reference as a result of the inspection, removing the main flexure from the load beam by cleaving the main flexure at a cleavage part disposed in a vicinity of the junction piece; and at least one time joining a sub-flexure having no junction piece to the load beam, from which the main flexure is removed.
摘要翻译：一种用于安装柔性挠曲件的方法，其具有固定到其上并具有一体的电磁转换元件的滑块的挠性挠曲件，其包括以下步骤：将具有用于接合负载梁的接合件的主弯曲部连接到负载梁与其间的接合片; 通过将电磁转换元件浮置在磁盘上来检查特性; 当特性不满足作为检查结果的参考时，通过在设置在接合件附近的劈裂部分断裂主弯曲而从负载梁移除主弯曲部; 并且至少一次将没有接合片的副挠曲件连接到所述负载梁上，从所述负载梁移除所述主弯曲部。
