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.

摘要： 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.

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.
