Abstract
A fixed disc drive type of memory storage devices includes an annular elastomeric pad that is engaged between the actuator base plate and a bowl-shaped lower casing. The pad is concentric with the spindle axis and forms an air-tight seal at the edge of a circular opening in the lower casing that prevents dust from entering the housing. The base plate has a circular platform portion with the hub for the spindle shaft being formed at its center. The circular form of the opening and platform portion are such that any temperature differential across the lower housing induces an oil-scanning type of deformation in the base plate so that the spindle does not tilt relative to the plane of motion of the transducers.
