    摘要: A system for positioning a transducing head in a disc drive device over a selected track of a rotatable disc includes an actuator arm which is rotatable about an axis, a head suspension mechanism connected to the actuator arm, and a slider carrying a transducing head and supported by the head suspension mechanism. A low resolution motor moves the actuator arm about the axis to effect coarse movement of the head between tracks of the disc. A piezoelectric element is embedded in the actuator arm to distort the arm to effect fine positioning of the head. Control circuitry distributes electrical signals to the low resolution motor and the piezoelectric element to selectively control movement thereof. The piezoelectric element is embedded in the actuator arm by removing a predetermined amount of material from the actuator arm and bonding the piezoelectric element in the resulting space in the actuator arm.

    摘要: An apparatus and method for reducing the effects of disc flutter or noise in a disc drive incorporates damping material or rings that are clamped or sandwiched against mounted information storage disc at a distance from a hub portion of a spindle assembly. The damping rings are positioned between a disc clamp and a bottom annular flange of the hub portion so as to engage and reduce vibrations in the mounted information storage disc or discs. The damping rings can be retained in grooves defined in the disc clamp, bottom annular flange and top and bottom surfaces of an annular disc spacer. Alternatively, the damping rings can be reatined on tubular sidewalls defined on the disc clamp, bottom annular flange of the hub portion and annular disc spacer. The arrangement of damping rings absorbs energy transmitted by vibrations in information storage disc and thus minimizes the effects of disc flutter in a disc drive.

    摘要: A clamp ring for a disk stack assembly of a computer disk drive unit includes a lower surface which includes an arcuate rolling contact surface that uniformly distributes a load applied to the clamp ring to components of the disk stack assembly underlying the clamp ring without damaging such disk stack components on load-induced flexion of the clamp ring. A cantilevered section of the clamp ring is disposed radially inwardly of the arcuate rolling contact surface, and is defined by a portion of the lower surface which is raised relative to an adjacent portion of the arcuate rolling contact surface so as to not contact the underlying disk stack components on load-induced flexion of the clamp ring. In use, the clamp ring is heated and then placed over the disk stack components to be clamped together. An axial load is applied to the clamp ring which causes it to flex and thus move contact between the lower surface of the clamp ring and the underlying disk stack components radially along the arcuate rolling contact surface. The axial force is maintained until the clamp ring cools sufficiently to hold the clamp ring in place, and then the axial load is removed.

    摘要: An apparatus and method for minimizing the risk of damage to a disc surface caused by contact between a disc and a slider in a head disc assembly of a disc drive. The apparatus includes a flexure and slider which are biased away from the disc when the disc is stationary and one or more aerodynamic airfoils attached to the flexure. The airfoils are attached to the flexure and extend from the flexure at an angle relative to the disc so as to interact with an air flow caused when the disc spins to force the flexure and the attached slider to move toward the disc during operation of the disc drive.
