ABSTRACT:
A base casting/cover for a magnetic storage system to minimize the impact of shocks and vibrations to the magnetic storage system. The base casting/cover of the present invention is weakened in the area to which the disk pack spindle shaft is attached, such that the pack bounce frequency and the spindle tilt frequency are separated by 20 Hz or more. The base casting/cover of the present invention is weakened by slits thereon in various configurations about the spindle shaft attachment area. The base casting/cover of the present invention further provides damping of the pack bounce frequency by covering the slits with an adhesive material.
