  • Patent number: 9153262
    Abstract: A head stack assembly (HSA) for a disk drive includes an actuator body having a cylindrical bore therethrough and an actuator arm extending therefrom. A head is attached to a distal end of the actuator arm. A pivot bearing cartridge is disposed within the cylindrical bore. A tolerance band is radially preloaded between an outer surface of the pivot bearing cartridge and an inner surface of the cylindrical bore. The cylindrical bore has a first diameter in a first region adjacent a first axial end, and a second diameter in a second region adjacent a second axial end. There is a radial step between the first and second regions. The first diameter is greater than the second diameter by at least 20 microns but no more than 100 microns.

  • Patent number: 8068314
    Abstract: A novel head stack assembly (HSA) is disclosed and claimed. The HSA includes an actuator including an actuator body and an actuator arm extending from the actuator body, and a flexible printed circuit (FPC) adjacent the actuator body. The FPC includes a slit therethrough. A head gimbal assembly (HGA) is attached to the actuator arm. The HGA includes a load beam, a laminated flexure attached to the load beam, and a head attached to the laminated flexure. The laminated flexure has a flexure tail that includes an intermediate region that is disposed adjacent the actuator arm, and a terminal region that is electrically connected to the FPC. The terminal region is substantially orthogonal to the intermediate region. The intermediate region of the flexure tail extends into the slit, interferes with the slit, and contacts and deforms the FPC adjacent the slit.

  • Patent number: 7706107
    Abstract: The present invention includes a flexible printed circuit bracket including a crash stop rubber and/or an air block. The air block directs the air flow from the rotating disk surface(s) away from the head gimbal assemblies to minimize positional variance of the read-write heads. The crash stop rubber contacts the crash stop stub on the actuator arm block, stopping actuator assembly swinging away from the disk. The invention includes making an actuator assembly with the invention's flexible printed circuit bracket, as well as making the hard disk drive. The invention includes both the actuator assembly and the hard disk drive as the products of these processes. The invention also includes the actuator assembly and the hard disk drive containing the invention's flexible printed circuit bracket.

  • Publication number: 20060146443
    Abstract: The present invention includes apparatus and methods for disk dampers with an inlet edge and/or an outlet edge, oriented and shaped to control airflow within the hard disk drive. The inlet edge and the outlet edge reduce the airflow turbulence at the actuator assembly. This improves the Position Error Signal (PES), as the read-write head accesses a rotating disk surface. The outlet edge may preferably be curved and oriented at an oblique angle with respect to the angular rotation of the disk(s) in the hard disk drive. The outlet edge may preferably extend over a section of a sector angle. The inlet edge may preferably be oblique, which helps to slow down the overall velocity of the airflow into the disk damper. This allows the tip of the inlet edge to be positioned closer to the actuator assembly than previously possible.
