摘要： Connecting pieces extend outward from the support plate in the opposite directions along a crossline. A flexure body is connected to the connecting pieces. A pad is fixed to the support plate at a position ahead of the crossline. A wiring pattern extends from a pad. The wiring pattern defines a first straight portion extending forward from the flexure body along a first straight line. A second straight portion extends along a second straight line intersecting with the first straight line. A curved portion connects the first straight portion to the second straight portion. The curved portion expands outward from at least one of the first and second straight lines. The support plate merely suffers from a bending at a position ahead of the imaginary crossline even if the solder generates a stress based on its shrinkage. The wiring pattern serves to absorb the stress.

摘要： A plate member is made of a metal material lighter than stainless steel in a suspension for a head slider. This leads to a reduction in the weight of the suspension. The natural frequency of the suspension is thus raised. Moreover, the viscoelastic member is interposed between the front surface of the plate member and the back surface of the flexure. This structure allows either the plate member or the flexure to act as a base and the other to act as a constraining member. In other words, the plate member, the flexure and the viscoelastic member in combination act as a so-called vibration damper including constraining layers. The viscoelastic member serves to further suppress vibration of the plate member and the flexure.

摘要： An arm has one end coupled to a head suspension and the other end defining a domed surface in a head suspension assembly. The domed surface establishes point contact against the side surface of a head slider. The arm is designed to restrain the direction of application of a force along an imaginary plane including the back surface of the head slider. A piezoelectric element is bonded to the arm at a position between the one end and the other end of the arm. The head suspension assembly allows the arm to curve in response to expansion/shrinkage of the piezoelectric element. A driving force is applied from the arm to the head slider based on the curvature of the arm. Since point contact is established between the arm and the side surface of the head slider, the curvature of the arm cannot be restrained.
摘要翻译：臂的一端联接到头部悬挂，另一端在头部悬挂组件中限定圆顶表面。圆顶表面与头部滑块的侧面建立点接触。臂被设计成限制沿着包括头部滑块的后表面的假想平面施加力的方向。压电元件在臂的一端和另一端之间的位置处结合到臂上。头悬挂组件允许臂响应于压电元件的膨胀/收缩而弯曲。基于臂的曲率，从臂向头滑块施加驱动力。由于在头部滑块的臂和侧表面之间建立点接触，所以不能抑制臂的曲率。

摘要： A mechanism for producing a minute movement of a head of a disk device, which simplifies wiring in a head actuator and reduces the cost of the device by decreasing the distance between adjacent carriage arms for putting a recording medium therebetween. The mechanism for producing a minute movement of the head is placed between the base portion of a head suspension and the leading end portion of each of the carriage arms of a rocking type head actuator. This mechanism consists of an actuator base fixed at the end portion of a carriage arm, a hinge plate attached to the base portion of a head suspension, and shearing type piezoelectric elements interposed between opposite surfaces of an actuator base and the hinge plate. A step portion is provided at an end portion of the actuator base. The piezoelectric elements are placed in a portion corresponding to the thickness of the carriage arm. This prevents the sum of the thicknesses of the actuator base and the piezoelectric elements from exceeding the height of the top surface of the carriage arm. Consequently, the height of the head actuator is reduced.

摘要： A retracting assembly produces a constant torque, in a data zone of a magnetic disk, which is greater than static friction of a bearing for a rotary actuator. However, in a parking zone on an outer portion of the magnetic disk, the retracting assembly generates a torque which suddenly increases so that a large holding torque is obtained and a magnetic head is reliably locked.
