摘要： An apparatus, method and combination for dissipating vibration from a head suspension of a data storage device. The combination includes a rotating disc in a data exchange relationship with a read/write head supported by a head suspension formed by the method. The method includes the steps of; forming a mounting region and a load beam region each adjacent a bend region; removing material from the bend region to form an aperture, a strut, an isolation aperture and a damping material support structure; and affixing a damping material to the strut and the damping material support structure. The apparatus includes the bend region adjacent both the mounting region and the load beam region, with the damping material attached to the strut as well as to the damping material support structure. The load beam region includes a rigid portion, which supports a flexure upon which a read/write head is attached.

摘要： One embodiment of the present invention provides a unified suspension that includes an integral, continuous laminate, which has a thick actuator arm portion, a thin pre-load portion, and a beam portion, all formed of the same single laminate. The pre-load portion is integrally connected to the actuator arm portion, is thinner than the actuator arm portion, and is configured to apply a pre-load force. The beam portion is integrally connected to the pre-load portion, and is configured for attaching a gimbal to it. This integral, continuous laminate substantially lowers the mass of the suspension, provides excellent shock, resonance and lift tab performance, lowers power consumption requirements, and simplifies the complexity and cost of manufacturing components for a suspension and for assembling the components of the suspension together and into a larger system of which the suspension is a part.

摘要： A system and a method for increasing suspension resonance frequencies of a head suspension assembly of a disc drive includes, in one example embodiment, attaching a base plate to an actuator arm assembly of the disc drive such that the base plate including the actuator arm assembly are in actuating relationship with a rotating disc of the disc drive. A two-piece suspension member having a first and second pieces is attached to the base plate. A gimbal is attached to the two-piece suspension member such that a predetermined bendable area is formed between the first and second pieces and on the gimbal having a stiffer preload bend radius. A stiffer preload bend radius provides a higher stiffness-to-mass ratio without increasing the spring rate of the head suspension assembly to increase suspension resonance frequencies of the head suspension assembly to fall outside a bandwidth of a servo drive to reduce off-track motion of the head suspension assembly during track follow-and-seek operations of the disc drive.

摘要： A head gimbal assembly includes a gimbal, a slider, and a polymer layer. The gimbal comprises a metal layer, and the metal layer of the gimbal defines a gimbal mounting portion for attachment to a metallic load beam and a gimbal tongue extending from the gimbal mounting portion. The slider comprises a ceramic material for carrying a transducing head, and at least a portion of the slider is secured to the gimbal tongue. The polymer layer is positioned adjacent to the gimbal and configured for limiting ceramic-to-metal and metal-to-metal contact.

摘要： A suspension is disclosed that includes a pre-load section and a load section. The pre-load section is configured to be connected to a base. The load section is connected to the pre-load section and comprises a load beam portion, a flex circuit portion, and a brace. The brace extends laterally exterior to the load beam portion proximate to the pre-load section. The brace increases the lateral sway vibration mode of the load section, allowing the load beam portion to be narrower, and provide a decreased weight and increased torsion vibration mode, while also maintaining an increased lateral sway vibration mode.
