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.

A magnetic disk drive system that has a suspension assembly that includes a slider having a heating element and a suspension configured with a protective structure that protects the heating element. The heating element of the slider can extend through the suspension to extend from the suspension assembly from a side that is opposite the slider. The protective structure is configured to protect the heating element and to prevent the heating element from contacting the heating element of an adjacent suspension during an event such as a physical shock to the disk drive system.

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.

Disclosed herein are embodiments directed to a head gimbal assembly including a novel suspension assembly that includes a flexure tail with a first plurality of apertures in its structural layer. Each of the first plurality of apertures underlies a first trace but not a second trace. Each of a second plurality of apertures in the structural layer underlies a second trace but not the first trace. Each of the first plurality of apertures includes a corresponding region of maximum width, and each of the second plurality of apertures includes a corresponding region of maximum width, as measured in the width direction. None of the corresponding regions of maximum width of the first plurality of apertures is disposed in an overlapping position along the long axis as any of the corresponding regions of maximum width of the second plurality of apertures.

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.

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.

A disk drive suspension assembly includes a load beam, a first hinge arm, a second hinge arm, a base plate, and a flexure that includes a head mounting surface. The base plate has a first base plate layer that includes a first base plate side and an opposing second base plate side. The first base plate side has a main base plate surface and a recessed base plate surface parallel to and offset from the main base plate surface. A first hinge arm is attached to the main base plate surface. A second hinge arm is attached to the recessed base plate surface. The first and second hinge arms are attached to the load beam. The base plate has a first thickness at the main base plate surface and a second thickness at the recessed base plate surface that is the same as the first thickness.
