ABSTRACT:
A disk drive comprises a cover plate with preload tension formed across the cover plate for increasing the stiffness of the cover plate. The preload tension is formed across the cover plate after the cover plate that was warped is secured to a base member of the disk drive to become un-warped. Such a cover plate with increased stiffness is not easily deformed and effectively minimizes propagation of noise generated from operation of the disk drive.
