摘要： Method for the removable sealing of a component housing, and apparatus to practice the method using an elastic or conformable sealing band. The present invention teaches a sealing band, preferably elastic, to apply a horizontal seal to the horizontal seam defined by vertically assembled component case elements. The seal is maintained in position over the seam by an alignment element disposed on at least one of the seal and the case. The sealing band is rendered electrically conductive by admixing therewith a conductive material, or by plating thereon a conductive coating. A retaining element may be further added to at least one of the sealing band and the case to minimize tampering with the sealing band once installed.

摘要： A disc mounting system for mounting the discs of a disc drive in a fixed radial relationship to the hub of a spindle motor. The disc mounting system includes curved spring elements, having a substantially C-shaped cross section, which are curved on a radius greater than the radius of the central opening of the discs. One or more spring elements are utilized with each disc, and assembly tooling is used to bend the spring elements so that the discs, with the opening of the C-shaped springs engaging the inner diameter of the discs, can fit over the hub of the spindle motor. The assembly tooling is then removed to allow the spring elements to partially straighten, firmly engaging the discs relative to the spindle motor hub in the radial direction. In a first embodiment of the invention, alternative mechanisms are disclosed for establishing the axial positions of the discs. In a second embodiment, a plurality of annular grooves are provided in the spindle motor hub and the spring elements engage both the discs and annular grooves in the spindle motor hub to fixedly locate the discs relative to the spindle motor hub in both the radial and axial directions. Fabrication of the spring elements from a shape-memory alloy is also disclosed.

摘要： Differing gram loads and actuator arm resonances are compensated for through the method and apparatus of positioning z-height of outer actuator arm at an optimal height. Specifically, an actuator arm driven by a closed loop servo motor system for a disc drive system is configured so that the outer upper and lower actuator arms are positioned at an optimum distance, called optimum z-height, from the disc surface. At the optimum z-height position, the gram load of the outer actuator arms are shifted as near as possible to the gram load of the inner actuator arms. At the optimum z-height, the resonances on the head gimbal assemblies of the inner and outer actuator arms are closest.

摘要： A disc mounting system for mounting the discs of a disc drive in a fixed radial relationship to the hub of a spindle motor. The disc mounting system includes a disc mounting ring associated with each disc in the disc stack. The disc mounting ring includes at least one axially extending finger against which a portion of the inner diameter of the disc is brought to bear in an interference fit. In a first embodiment of the invention, the disc mounting ring includes a single finger and that portion of the inner diameter of the disc radially opposite the finger directly contacts the spindle motor hub. In other embodiments of the invention, the disc mounting ring includes a plurality of fingers spaced circumferentially about the ring and the inner diameter of the disc bears on all fingers and has no direct contact with the spindle motor hub. In all embodiments, it is envisioned that sufficient axial force will be applied to the discs at the time of manufacture to produce some cold-flowing of the disc mounting ring material of the fingers. Mechanisms for controlling the axial location of the discs relative to the spindle motor hub are also disclosed.
