摘要： The invention is a hard-disk-drive (HDD) assembly that includes a flame having the exterior dimensions of a particular form-factor HDD, an HDD with a form-factor smaller than the frame, a pair of mount assemblies that support the HDD entirely within the larger form-factor frame, and an electrical cable located entirely within the frame and having one end connected to the HDD and the other end exposed to the frame exterior at the position determined by the specifications of the larger form-factor. The HDD assembly thus presents a smaller form-factor HDD as a fully plug-compatible alternative to a larger form-factor HDD. The mount assemblies have spring-like cantilever arms in contact with damping material to provide a highly-damped nonlinear spring system that provides mechanical-shock resistance for the HDD in a direction normal to the planes of the disks and high stiffness in a direction parallel to the planes of the disks.

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.

摘要： Dynamic fly height (DFH) controlled read/write heads using multiple heaters have their heater powers set within a range of ratios that allows minimum clearances to be set between the read-gap and the write-gap and the surface of a disk, thereby providing improved touch-down detection. Determining the correct range of power ratios requires varying the ratio to create an adjustable protrusion profile for the read and write elements in the head and measuring values of the ratio and corresponding values of read gap and write gap clearances that create points of minimum clearance. By adjusting the ratio of power supplied to the heaters, different protrusion profiles can be produced, clearance control for sigma reduction can be obtained and read/write readiness and operation consistency and reliability can be improved.

摘要： A method to compensate for spacing variations between a dynamic fly height (DFH) controlled read/write head and a rotating disk surface. Using a HDI sensor or equivalent indicator of touchdowns, a power profile is calculated for an arbitrary track on a disk. The profile tracks disk topography by recording touchdown power at each of a series of sectors into which the track is subdivided. The resulting power profile, smoothed and expressed as a function of sector position, substitutes for the usual constant TD power setting that provides only an uncompensated range of spacing variations. A fixed back-off spacing power is added to the power profile enabling the head to fly over the track at a constant spacing. The power profile can be calculated to account for various temperature and pressure conditions.

摘要： A write-inhibit signal is generated by a head-disk interaction sensor during a write process that is integrated with a suspension of a hard disk drive (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.
