ABSTRACT:
A data storage device is provided with an area on the surface of the baseplate adjacent a thrust bearing surface of at least one rotating component of the device is modified to control interface friction between the component and the baseplate. The surface quality is enhanced by altering the roughness of the surface by embossing or machining the baseplate, preferably in areas beneath the rotating component.
