    摘要: A head-gimbal assembly (HGA). The HGA includes a deformable plate affixed to a load beam, a piezoelectric element affixed to the deformable plate, and a base plate affixed to the deformable plate. The deformable plate includes: a hole; a first section in front of the hole and affixed to the load beam; a second section behind the hole and affixed to the base plate; and, first and second spring members that join the first section and the second section, can deform in a front-back direction, and are positioned to sandwich the hole in a left-right direction. The piezoelectric element is affixed between the first section and the second section. The base plate includes projection members on a front edge of the plate and projecting out toward the first section. The front edges of the projection member are positioned further to a front edge than a back edge of the hole.

    摘要: Embodiments of the invention improve the impact-resisting performance of a disk drive. In a head actuator assembly according to an embodiment of the invention, the difference in resonance frequency between an arm bending mode and a coil bending mode is set at a predetermined value or less. Since there is a phase difference between these two modes, an oscillation gain in the arm bending mode can be greatly decreased by approximating the two resonance frequencies to each other. Consequently, it is possible to suppress collision of a head with a recording disk caused by an external shock and thereby improve the impact-resisting performance of a disk drive.

    摘要: Approaches for integrated lead suspension that provides many benefits, such as enabling a dual stage actuator (DSA) to be used with a single layer flex with a reduced amount of crosstalk. An integrated lead suspension comprises a tail end having a plurality of conductive pads positioned thereat. The plurality of conductive pads includes a first and second dual stage actuator (DSA) pad. The first and second DSA pads are electrically coupled to a conductive member by way of conductive vias. The conductive member may be a stainless steel island. The first DSA pad conducts a signal to a first terminal at each of a plurality of dual stage actuators, while a second terminal at each of the plurality of dual stage actuators is connected to ground.
