    摘要: A cam spreader having a substantially rigid body with a proximal end defining a handle and a distal end defining a cam. The cam has at least a first lobe, the first lobe having an outer surface in a first quadrant of the cam as viewed in cross section along a longitudinal central axis of the body. At least a portion of the outer surface, or profile, of the curve is mathematically driven and produces a constant incremental lift.

    摘要: A magnetic head element linear actuator assembly including a base, a platform, a core, a coil, a plurality of slats and a plurality of magnetic bars. The platform is positioned opposite the base and is configured to maintain a magnetic recording head. The core is disposed between the base and the platform such that a space is defined between the core and the platform. The coil is wound about a central axis of the core. The plurality of slats rigidly maintain the platform relative to the base. Further, the plurality of slats are deflectable from a straightened state and are biased to return to the straightened state following deflection. Finally, the magnetic bars are secured to respective ones of the plurality of slats adjacent the coil. With this configuration, a magnetic field generated by the coil induces deflection of the plurality of slats via the magnetic bars. In response, the platform moves linearly toward the base.
