ABSTRACT:
A vibration control device for controlling vibration of a disc drive supported in a compartment of a mass storage array. Disc drives stored in a compartment of a mass storage array may move within the compartment during operation of the mass storage array. Movement of a disc drive in a compartment may affect the performance of the disc drive to retrieve data from and write data to selected data tracks of a disc. In particular, vibration along an extent of the disc drive aligned with an operational stroke of the actuator mechanism may skew the operational stroke of the disc heads supported via the actuator mechanism. The vibration control device includes a spring which is adapted to exert a biasing force to a disc drive inserted into a compartment to restrict movement of the disc drive within the compartment.
