摘要： A method of controlling the spring rate of a spring region of an unassembled or partially or fully assembled load beam for a disk drive head suspension by providing the spring region with a number of bridges which may then selectively opened to achieve a target spring rate. Adjusting the spring rate in this manner provides control of resulting performance characteristics of the head suspension. In one aspect, a data set of spring rate reductions corresponding to bridge sets removed is predetermined and used with the corresponding type of load beam to determine the bridges to remove to approximate the target spring rate.

摘要： A switchable shunt has an insulating layer separating conductive lead and spring metal layers. The shunt includes a base region formed on the spring metal layer, one or more arms formed in the conductive lead layer and at least one of the insulating and spring metal layers, one or more pad regions electrically coupled to an arm and formed in at least the conductive lead layer, and one or more gaps. Each arm extends through a gap and is resiliently biased toward a shunted state with the pad region in electrical contact with the base region. The shunt is movable to an electrically open state where the pad and base regions are electrically isolated. A method of making the shunt includes etching the shunt from laminated material and pushing the arm and pad through the gap. The shunt may be operated by applying a force to the arm.

摘要： An actuator assembly having a plurality of head suspensions removably secured to a plurality of arm regions of the actuator assembly. Each arm region of the actuator assembly includes a spring mount which can be compressed or expanded from a neutral state to a stressed state to engage an engagement structure on the head suspension for removably securing the head suspension to the arm region. In one embodiment, the spring mount is comprised of a pair of spring arms having holes formed in the spring mount that engage a plurality of vertical pins formed in a mounting region of the head suspension. The spring arms are urged from the neutral state, the pins are inserted through the holes in the spring arms, and the spring arms are released to engage the pins, and thereby hold the suspension in place. In a second embodiment, the spring mount includes a boss mount having a pair of members extending in a transverse direction from the spring arms. The transverse members of the boss mount each include a concave surface that engages a boss extending from the mounting region of the head suspension upon the compression or expansion of the boss mount from the neutral state to the stressed state. Upon release of the boss mount, the concave surfaces of the boss mount engage the boss, thus providing an engagement force that securely holds the head suspension in place in the actuator assembly.

摘要： An integrated lead suspension flexure including a metal spring layer having a metal base region, a metal head bonding platform, and one or more metal spring arms connecting the metal head bonding platform to the metal base region for flexure motion. The flexure also includes a conductive lead layer having a surface facing the metal spring layer and extending between the metal base region and the metal head bonding platform. The conductive lead layer has lead base region portions extending over the metal base region, lead metal-backed arm portions extending over the metal spring arms, and lead suspended portions extending from at least one of the lead metal-backed arm portions. The flexure further includes a hygroscopic insulator layer between the metal spring layer and the conductive lead layer having insulator base region portions for bonding the lead base region portions to and insulating the lead base region portions from the metal base region, insulator metal-backed arm portions for bonding the lead metal-backed arm portions to and insulating the lead metal-backed arm portions from the metal spring arms, and insulator suspended portions on the lower surface of the lead suspended portions. A first curvature is induced on each insulator metal-backed arm portion and a second curvature is induced on each insulator suspended portion when the insulator layer undergoes volumetric variations. The insulator metal-backed arm portions and insulator suspended portions have a serial arrangement so that the direction of the first curvature opposes the direction of the second curvature.

摘要： A head suspension assembly including a load beam having a rigid region, a mounting region on a proximal end of the load beam, and a flexure on a distal end of the load beam. The flexure has a read/write head attachment region for supporting a read/write head on the distal end of the load beam. Deformation of the head suspension assembly displaces the head attachment region. A strain transducer circuit that acts as a strain gauge is mounted on the head suspension assembly. The resistance of the transducer circuit varies with strain in the circuit, which, in turn, varies with displacement of the read/write head. The magnitude of resistance change of the transducer circuit indicates the magnitude of head off-neutral motion.

摘要： A load beam for a head suspension has high lateral and torsional stiffness across the entire length of the load beam to assure high lateral bending and torsional resonance frequencies. The load beam utilizes an optimized top profile for distributing mass transversely of the load beam and over the longitudinal length of the load beam in a way to increase lateral stiffness and torsional stiffness. To increase lateral stiffness, a wider and/or thicker region is provided near the actuator mounting side of the load beam, while torsional stiffness is enhanced by taking mass away from the outside edges in the remainder of the load beam extending toward its distal tip. A load beam top profile is defined by side edges, each providing a spring region and a proximal portion of the rigid region, a curve having a center of curvature within the load beam structure, while a more distal portion of the rigid region is defined by curves having a center of curvature outside the load beam material. Preferably, a stiffener member is provided covering at least a portion of the surface of the rigid region. The stiffener is wide where it covers the proximal portion of the rigid region for increasing lateral and torsional stiffness, and then decreases in width extending toward the distal end of the load beam.

摘要： A head suspension for attachment to an actuator arm and for supporting a head slider within a rigid disk drive includes a load beam having a gimbal region provided adjacent a distal end of the load beam with a slider receiving aperture. A slider bond pad separately provided from the load beam is supported within the aperture by at least one conductive trace that also connects the slider bond pad to the load beam. An end portion of the conductive trace defines a gimbal axis about which the slider bond pad can rotate, and the slider bond pad is connected to the end portion of the conductive trace so that the majority of the slider bond pad is located to one side of the gimbal axis.

摘要： A system for adjusting the gram load, static attitude roll and radius geometry of a suspension with a high degree of accuracy and repeatability includes a clamp, load-engaging member, actuator, laser and control system. The mounting region of the suspension to be adjusted is releasably received and clamped by a clamp. A load beam of the suspension is engaged and supported at adjust positions with respect to the clamp by the load beam-engaging member. The load beam-engaging member is driven and positioned by the actuator. IR light from the laser is directed to the spring region of the suspension by optical fibers. The control system includes a pre-adjust input terminal, memory and a controller. Information representative of a measured pre-adjust fly height gram load, static attitude roll and radius geometry values of the suspension are received at the pre-adjust input terminal. Adjust data representative of load beam adjust positions which will cause the suspension to have a desired post-adjust fly height gram load, static attitude roll and radius geometry values after the load beam is stressed relieved is stored in the memory. The controller is coupled to the pre-adjust input terminal, actuator, laser and memory, and controls the system by: 1) accessing the memory as a function of the measured pre-adjust fly height gram load, static attitude roll and radius geometry values to determine the load beam adjust position which will cause the suspension to have the desired fly height gram load, roll and radius geometry values after the load beam is stressed relieved, 2) actuating the actuator and causing the load beam-engaging member to position the load beam at the adjust position, 3) actuating the laser to stress relieve the spring region of the load beam while the load beam is positioned at the adjust position, and 4) actuating the actuator and causing the load beam-engaging member to release the load beam after the load beam is stress relieved.
