Abstract
A disk drive includes a data storage disk attached to a spindle which is rotatably mounted to a housing. A support shaft is also mounted to the housing parallel to the spindle, and includes an arm supported thereon parallel to the disk. A rib extends along the housing between the spindle and the support shaft for synchronizing fundamental resonant vibration thereof due to a shock load to couple in phase vibratory motion thereof. The support shaft may pivot and carry a suspension arm and data access head, or the shaft may be stationary and carry a load-unload ramp for parking the suspension arm, or both types of shafts may be used in the housing with corresponding ribs extending to the common spindle.
