ABSTRACT:
A vibration isolation apparatus and method for attenuating internal and external vibrations impinging on a data storage system housing is disclosed. A spindle motor assembly is mounted to a secondary base which is decoupled from a primary base of the housing. A compliant member is disposed between the secondary base and primary base which attenuates spindle motor induced vibrations that would otherwise be transmitted to the primary base and the actuator assembly. The actuator assembly may be mounted to a tertiary base which is also isolated from the primary base by a compliant member. The novel vibration isolation also provides for the dampening of external shock vibrations impinging on the housing and spindle motor assembly of the data storage system. An injection molding process is preferably employed to fabricate the novel data storage system housing base.
