摘要： A swage mount for a recording head suspension comprising a flange, and a hub made of a base metal extending from the flange, and at least an outer surface of the hub is plated with one or more layers of metal which provides increased retention torque, and/or increased cleanliness, and/or increased corrosion resistance. This invention may be used in conjunction with swage mounts that contain surface protrusions that are intentionally created (such as chromium nitride or chromium carbide protrusions) or not intentionally created (such as material inclusions or embedded media particles). In this case the metal plating helps prevent separation of the protrusions from the swage mount, thereby helping to prevent contamination.

摘要： The present invention is a head support device which is thin and may assure excellent flexibility and shock resistance while applying a sufficient load to the head, and a disk drive using the device. Specifically, it comprises a support arm, and a head disposed at one end of the support arm, which is mounted on a head slider so as to be opposed to the recording medium, an elastic member such as a plate spring which renders the support arm an activating force in a direction vertical to the recording medium when the support arm comes to the rotational center in vertical rotation against the recording medium, and a holder connected to the elastic means, wherein when an external impact force is applied to the head slider, suppose the distance from the action point of load that activates the head slider toward the recording medium to the immovable point in the rotation of the head slider in the direction of pitch is Lo, and the length of head slider 1 in the direction of air flow is Ls, then 0.5

摘要： A suspension for disc drive comprises a base plate, a load beam attached to the base plate, and a flexure attached to the load beam. The load beam includes a rigid body portion, formed of a thick plate independent of the base plate, and a spring portion, formed of a spring member in the form of a thin sheet independent of the rigid body portion. The spring member connects the rigid body portion and the base plate. The spring member is thinner than the rigid body portion and has a lower spring constant. The spring portion is more flexible than the rigid body portion.

摘要： A low cost, flex head gimbal assembly has a substrate with an attachment region, a flexure region and an integrated gimbal. The flex head gimbal assembly is electrically and mechanically connected to an actuator arm via solder bumps in the attachment region. A stiff plate is attached to the substrate between the attachment region and the flexure region. A flex cable and electrical interconnections extend from the attachment region across the flexure region to the gimbal. Electrical leads extend from the solder bumps to the flex cable. The substrate is bent at the stiff plate to achieve the desired z-height and to impart the pre-load to the assembly.
