    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.
