摘要： Gimbal designs are provided that minimize adverse dynamic performance of a HDD suspension, particularly subsequent to head-disk-interface (HDI) interactions. The improvement of operational performance can be seen in graphical representations of the vibrational modes of a gimbal mounted slider subsequent to such HDI interactions. Each gimbal design includes a ramp limiter formed as two separated arms connected by one or two transverse bars and a routing of conducting traces that relieves stress and minimally contacts these bars.

摘要： In a suspension in a hard disk drive, a gimbal with asymmetric dynamic properties, in which the two halves of the gimbal may have different stiffness distribution or inertia distribution. Structural difference between the two halves, or materials with different stiffness, may cause the different stiffness distribution or inertia distribution. When the suspension vibrates, the different stiffness and/or inertia distribution increase the friction between the gimbal and a load beam of the suspension, and increase the damping of the suspension.

摘要： An apparatus and method for utilizing a small pad to increase a head to a disk interface reliability for a load/unload drive. The method provides a suspension for reaching over a disk. A slider having a read/write head element on a trailing edge (TE) portion is also provided, the slider coupled with the suspension. In addition, a low friction zone is provided proximal to a leading edge (LE) portion of the slider such that when the LE portion of the slider is aligned to contact a disk element during the load phase, the low friction zone contacts the disk element and provides a reduced contact area with respect to the LE portion of the slider such that a friction force is reduced and the slider can assume a proper flying attitude.

摘要： A Hard Disk Drive (HDD) includes a write-inhibit signal that is generated by a head-disk interaction sensor during a write process that is integrated with a suspension of the HDD when fly-height modulation of the slider is detected during a write process. The suspension load beam includes a dimple and a laminated flexure. The laminated flexure includes a surface that is adapted to receive a slider and a surface that is adapted to contact the dimple. The head-disk interaction sensor is fabricated as part of the laminations of the flexure. The head-disk interaction sensor can be an accelerometer that senses an acceleration of the flexure when the slider contacts the disk of the disk drive and/or a pressure sensor that senses a pressure between the flexure and the dimple when the slider contacts the disk. A write-inhibit circuit is responsive to the sensor signal by inhibiting the write process.

摘要： A mechanical-shock-mount assembly enables attachment of a mechanical-shock-sensitive electronic device to a support structure. Two identical shock-mount structures are attached and located on opposite sides of an electronic device. Each shock-mount structure has a pair of generally planar spring-like cantilever beams that have their free ends for attachment to the support structure. Damping material is located on the surfaces of the cantilever beams between the beams and clamping surfaces. At least one clamping surface is a plate that compresses the damping material between itself and the beam and/or compresses the damping material between the beam and a surface of the support structure when it is attached to the support structure. This shock-mount structure acts as a highly-damped nonlinear spring system that provides mechanical-shock resistance for the device in a direction perpendicular to the cantilevered beams and high stiffness in a direction in the plane of the beams. If desired, the shock-mounts can be first assembled to the support structure before attaching the device. The support structure can optionally have additional features for attaching other components of the device host.
