Abstract: A disk cartridge has a projection on an inner surface thereof. The projection is located proximate the head access opening to prevent medium distortion during cartridge insertion. The cartridge is designed for insertion into a drive in which the medium is mounted by translating the medium within the cartridge away from a spindle access opening in the cartridge. The translation of the medium can cause the medium to twist thereby distorting the peripheral edge of the medium. The projection on the inner surface of the cartridge inhibits the medium distortion.

Abstract: A ring shaped-disk clamp for clamping a disk stack to a spindle motor. The ring-shaped disk clamp is referred to as a shrink-fit disk clamp and must be expanded by heating prior to being inserted onto the hub of a spindle motor. Once inserted onto the hub of the spindle motor, an external axial load is applied to the disk clamp. As the disk clamp cools while applying the external load, the clamp contracts and provides a gripping force on the hub of the spindle motor. Subsequently, the external load is removed. The ring-shaped disk clamp includes a top surface, a bottom surface for contacting the disk stack, and an inner peripheral surface for contacting the hub. The inner peripheral surface contacts the hub at a hub contact area that is optimized to provide a localized gripping force on the hub. By optimizing the location of the hub contact area, the disk clamp can provide a relatively high gripping force with a low coefficient of friction between the disk clamp and the hub.

Abstract: In a dynamic pressure bearing apparatus having a fixed shaft, dynamic pressure generating grooves formed at least on one side of circularly facing surfaces of a rotor and of the fixed shaft which is rotatably meshed with the rotor, a radial bearing formed in an axial direction and a thrust bearing is formed by one end of the fixed shaft and axially facing surfaces of the rotor, the rotor is rotatably supported against the fixed shaft by air dynamic pressure which is generated in the radial bearing and the thrust bearing. The radial dynamic pressure bearing generating grooves are formed on the radial bearing in a dynamic pressure groove shape which pumps air pressure toward the thrust bearing side. An air guide hole is formed in the fixed shaft from the one end to another end of the fixed shaft. The dynamic pressure bearing apparatus comprises the thrust bearing, a pressure chamber, which stores air pumped from the radial bearing between the one end of the fixed shaft and the surface of the rotor facing the one end in the axial direction and a pressure adjuster constructed with small air passages from the pressure chamber and the air guide hole.

Abstract: A disk clamping device in a magnetic disk drive includes a clamper which presses an uppermost one of a plurality of magnetic recording disks and a clamping force transmission member which presses the clamper against the uppermost magnetic recording disk. A material having a small Young's modulus, such as a polymeric material and a super elastic material, is used for the clamper or the clamping force transmission member, or both of them. The device may include a shim whose Young's modulus is larger than that of the clamper. The clamping force of the clamper is transmitted to the uppermost disk through the shim. The arrangement makes it possible to reduce the variations in the clamping force caused by a lack of manufacturing precision or a change in temperatures and to provide a stable clamping force. The uniform clamping force reduces the occurrence of undulation in the disks otherwise caused by the circumferential clamping force differences in the clamper.

Abstract: A disk storage drive for a disk storage device having a clean chamber for a storage disk having a central opening is provided with a brushless drive motor. The drive motor includes a stator and a winding on the stator and further includes a shaft aligned with the rotation axis of said motor, and a magnetically conducting member supported for rotation about the rotation axis and having an inner wall coaxially surrounding the stator. A magnet fixed to the inner wall of the magnetically conducting member is radially spaced from the stator. The disk storage device further includes a hub positioned within the clean chamber and contiguous with the magnetically conducting member so that the hub and the magnetically conducting member together form an outer rotor of the drive motor. The outer rotor has a radially extending flange having a surface which supports said storage disk. A support member contiguous with a portion of a partition of the clean chamber supports the shaft and has a recess receiving a portion of said radially extending flange, whereby the spacing between opposing walls of the clean chamber is reduced. Further, the magnetically conducting member comprises magnetic shield means at least peripherally surrounding the stator and at one end radially extending to the bearing and shaft assembly, and the rotor has a radially extending inner wall spaced closely adjacent to said stator windings, whereby said disk storage device is compact in a direction along said disk rotation axis while said motor magnet is axially separated from the plane of said storage disk.

Abstract: A process for assembling a clamp ring to a disk stack assembly of a computer disk drive unit. The clamp ring 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.

Abstract: A spindle shaft attachment technique for a disk drive includes a conical tip formed on, or added to, the top of the spindle shaft in order that it might be embedded in or contact a substantially planar, interior surface of the HDA cover at a location determined by the perpendicularity of the spindle as set by the baseplate without forcing the top of the spindle shaft to a predetermined screw hole or recessed cone location on the cover. The spindle shaft attachment technique disclosed allows for use of a relatively longer spindle shaft for a given height form factor drive and, therefore, allows a greater spacing between upper and lower spindle bearings resulting in greater stiffness and an increased rocking mode frequency.
