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 mechanism is provided to position a transducing bead with respect to a selected radial track of a rotatable recording disc in a disc drive including an actuator arm and a suspension load beam connected to the actuator arm. A plate is hingedly attached to the load beam, and a flexure is attached to the plate. A slider supporting the transducing head is attached to the flexure. A microactuator is attached to the plate and is operable in response to electrical control signals to move the plate relative to the load beam in the general plane of the load beam to selectively position the transducing head proximate to the selected radial track on the rotatable recording disc.

摘要： An apparatus for a disk drive having at least one disk mounted in a housing having a controlled environment defined by the housing. Such a disk drive generally includes, within the controlled environment, one or more transducers for reading information from and writing information to the disk, and at least one actuator for selectively positioning the transducers with respect to the disks. Each actuator includes at least one magnet for providing a magnetic field and an actuator coil, mounted on the actuator, arranged so that a current in said coil creates a force to pivot the actuator. The apparatus comprises a magnet shield encasing each such magnet for preventing matter, generated during the decomposition of said magnet over a period of time, from interfering with the operation of the disk drive.

摘要： A disc drive and method of making a disc drive, including a voice coil magnet assembly. The voice coil magnet assembly includes a top magnetic return plate, a bottom magnetic return plate and at least one pair of magnets affixed to at least one of the plates. The voice coil magnet assembly is pre-assembled prior to attachment to a base plate. The pre-assembled voice coil magnet assembly is then structurally coupled to the base plate at a boss or attachment point, and is done so in a rotatable manner at the boss or attachment point, such that the voice coil of an actuator assembly is sandwiched by the rotation of the pre-assembled unit about the structural attachment point or boss.
