摘要： Swaging a suspension base plate to an actuator arm for a hard disk drive. A portion of material adjacent to a hole in the actuator arm is removed to create an opening to receive material. A flange of the suspension base plate is inserted into the hole in the actuator arm. The suspension base plate is swaged to the actuator arm, wherein the swaging causes material from the suspension base plate to flow into the opening.

摘要： An interleaved conductor structure for electrically connecting the read/write electronics to a read/write head in a hard disk drive is provided. The interleaved conductor structure may allow for an increased characteristic-impedance range, greater interference shielding and a reduction of signal loss that is contributed by a lossy conductive substrate. The electrical traces may have different widths, be offset, or even wrap around each other at the via connections.

摘要： A head suspension for a head/gimbal assembly comprises a flexure attached to a load beam. The load beam includes a lifter tab configured to engage a lifting surface of a load/unload ramp. The flexure includes a limiter tab, extending from a trailing edge thereof, that is configured to engage with a gimbal-limiting surface of the load/unload ramp. The limiter tab comprises a metallic base layer, a metallic stiffening layer, and a non-metallic intermediate layer disposed between the base and stiffening layers. The stiffening layer can include both conductive traces that terminate with a set of bonding pads and an appendage that extends along a length of the limiter tab. The appendage portion of the stiffening layer serves to increase the thickness of the limiter tab to increase the stiffness of the limiter tab.

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.
