摘要： A head suspension for a reverse flow disk drive. The head suspension includes a load beam having a mounting region at a proximal end, a rigid region at a distal end and a spring region between the mounting region and the rigid region. A flexure is mounted on the distal end of the rigid region. A slider is mounted on the flexure. The slider has a proximal end closest to the proximal end of the load beam, wherein the spring region, the rigid region, the flexure and the slider comprise an active portion. One or more read/write heads are located on the proximal end of the slider. A plurality of electrical traces extend along the head suspension to the proximal end of the slider. At least one airflow attenuator is provided that creates a region of reduced airflow velocity proximate at least a portion of the active portion. An actuator assembly and to a reverse flow disk drive are also disclosed.

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 novel head stack assembly (HSA), and method for HSA assembly, are disclosed and claimed. A first flexure tail has a long axis approximately parallel to a side of the actuator arm. The actuator arm includes a slot in the side having a slot end. The first flexure tail is disposed partially within the slot. The first flexure tail includes a first raised region in contact with the slot adjacent the slot end. The first raised region includes an out-of-plane bend with cross-sectional curvature along the long axis. The first raised region may be squeezed while inserting the first flexure tail partially within the side slot, with the first raised region adjacent the slot end, and then allowed to expand into contact with the slot adjacent the slot end.
