REDUCING VIBRATION OF DATA STORAGE DEVICE IN A DATA STORAGE SYSTEM

摘要

A data storage system may include multiple data storage devices, such as hard disk drives, a cooling fan, and a sound balancer structure between the fan and the drives. The sound balancer is intentionally positioned where it substantially balances, about the center of rotation of and along at least one axis of a fan-facing storage device, the sound pressure from the fan that impinges upon the fan-facing face of the storage device. This redistribution of the sound pressure suppresses sound pressure-induced torque upon and therefore rotational vibration of the storage device, which in turn enhances the track following capability of the storage device.
