摘要： A head suspension for supporting a head slider relative to a rotating disk in a rigid disk drive, formed from a flexure and a load beam that has a mounting region, a rigid region and a spring region located between the mounting and rigid regions. The load beam including a shock limiter integrally formed within the spring region as a cantilevered portion surrounded by a spring aperture used for adjusting the spring stiffness of the spring region. The head suspension typically configured to include a bend or radius in the spring region to bias the head suspension toward the disk surface. The cantilevered portion of the shock limiter formed with a pre-determined gap between the shock limiter and the head suspension when the head suspension is in an operating position. The cantilevered portion configured to overlap a portion of the head suspension, such that movement of the head suspension toward the shock limiter due to impact or shock loading results in contact between the shock limiter and the overlapped portion, thereby arresting the movement of the head suspension.

摘要： A magnetic disk drive head suspension of the type having a load beam, a mounting region, and a flexure, includes an improved load point dimple. The load point dimple can be formed in either the load beam for contacting the flexure or the flexure for contacting the load beam. The dimple is characterized by a conical shape, including a conical base portion with generally planar surfaces of the dimple and a spherical tip of the dimple. The tip of the dimple is formed to have a height that is greater than the radius of curvature, and so that the radius of curvature of the tip is less than one-half the width of the dimple as measured at a surface of the material from which the dimple extends. In a preferred embodiment, the radius of curvature of the tip is approximately equal to the protrusion of the dimple above the surface in which the dimple is formed to reduce the change in the high point location of the dimple caused by a deflection angle in the surface in which the dimple is formed.
