HYDRODYNAMIC FLUID BEARING CONTAINING LUBRICANTS WITH REDUCED BUBBLEFORMING TENDENCY FOR DISK DRIVE APPLICATION

摘要

A disc drive storage system includes a housing having a central axis, a stationary member that is fixed with respect to the housing and coaxial with the central axis, and a rotatable member that is rotatable about the central axis with respect to the stationary member. A hydro bearing interconnects the stationary member and the rotatable member and includes a lubricating fluid having a base fluid and an additive for reducing the tendency of bubble formation in the lubricating fluid.
