摘要： A head suspension assembly includes (a) a slider having a head for recording into/reproducing from a record medium, mounted thereon, (b) a load beam having (i) the slider disposed via a flexure at one end, and (ii) a leaf-spring-like resilient member integrally formed therewith in the vicinity of the other end along the longitudinal centerline thereof, and (c) a carriage having a pair of pivots in contact with the load beam. The distal end of the resilient member is joined to the carriage and the resilient member has an opening (hole) in the center thereof. Because the stress occurring in the leaf-spring-like resilient member that is provided in the load beam of the head suspension assembly is reduced, the resilient member exerts sufficient urging force to the head and has high flexibility. This structure can provide a highly shock-resistant and thin head suspension assembly.

摘要： A head support device is thin and assures excellent flexibility and shock resistance while applying a sufficient load to a head. A disk drive uses the head support device. The head support device comprises a support arm, a head disposed at one end of the support arm, which is mounted on a head slider so as to be opposed to a recording medium, an elastic member such as a plate spring which provides the support arm an activating force in a direction perpendicular to the recording medium when the support arm comes to a rotational center in vertical rotation against the recording medium, and a holder connected to the elastic member. When an external impact force is applied to the head slider, with a distance from an action point of load that activates the head slider toward the recording medium to an immovable point in the rotation of the head slider in a direction of pitch being Lo, and a length of head slider in a direction of air flow being Ls, then 0.5
