Title
(EN) REDUCING VIBRATION OF DATA STORAGE DEVICE IN A DATA STORAGE SYSTEM
(FR) RÉDUCTION DES VIBRATIONS D'UN DISPOSITIF DE STOCKAGE DE DONNÉES DANS UN SYSTÈME DE STOCKAGE DE DONNÉES
Abstract
(EN)
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.
(FR)
L'invention concerne un système de stockage de données qui peut comprendre de multiples dispositifs de stockage de données, tels que des lecteurs de disque dur, un ventilateur de refroidissement, et une structure d'équilibreur de son entre le ventilateur et les lecteurs. L'équilibreur de son est positionné intentionnellement où il équilibre sensiblement, autour du centre de rotation d'et le long d'au moins un axe d'un dispositif de stockage faisant face à un ventilateur, la pression sonore provenant du ventilateur qui heurte la face orientée vers le ventilateur du dispositif de stockage. Cette redistribution de la pression sonore supprime le couple induit par la pression sonore sur et par conséquent la vibration rotationnelle du dispositif de stockage, ce qui à son tour améliore la capacité de suivi de piste du dispositif de stockage.
