摘要： A method of assembling an actuator arm for use in a disc drive is disclosed. The actuator arm includes a head gimbal assembly which supports a slider and magnetic head, and a slider supported from the gimbal. The actuator arm also includes a layer of Z-axis conductive adhesive film between the gimbal and the top surface of the slider for bonding the gimbal to the slider, and providing both mechanical support and electrical grounding for the slider.

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 printed circuit head interconnect of a head gimbal assembly (HGA) has different material thicknesses in different regions of the printed circuit head interconnect. The printed circuit head interconnect includes a lamination sheet of materials having dielectric materials and conductive materials. The regions which need to have a lower stiffness are made thinner than the rest of the regions. The rest of the regions are made thick and robust enough to support the HGA. A method of reducing the thicknesses of the printed circuit head interconnect includes applying a resist mask pattern having a plurality of openings with different sizes so as to obtain different thicknesses of the materials in different regions of the printed circuit head interconnect.

摘要： A slider scale package assembly in a head gimbal assembly (HGA) for electrically coupling a slider/magnetic recording (MR) head to a head interconnect circuit in a disc drive includes a flex circuit attached to the back of the slider/MR head which turns the slider/MR head into the slider scale package with at least one repositioned interconnect pad disposed at the back of the slider/MR head. The flex circuit further includes a conductive material, one end of which is electrically bonded to a bond pad of the slider/MR head, and the other end is electrically bonded to a conductive material of the head interconnect circuit via the interconnect pad. A plurality of flex circuits can be made in a sheet format and dividable into a plurality of individual flex circuits to be attached to a plurality of slider/MR heads. The bonding of the conductive material of the flex circuit to the slider/MR head and the bonding of the interconnect pad of the flex circuit to the conductive material of the head interconnect circuit can be done in a separate automated process.
