ABSTRACT:
A flexural bearing for an actuator assembly of a magnetic-disk drive includes a first and a second resilient member (10 and 12) and a third resilient member (14). The resilient members are attached to a base plate (40) of the disk drive and pivotally support an actuator body (16). The third resilient member includes an tensioning spring (18). The first and second resilient members are coupled to the base plate at two distinct locations and share a common anchor point on the actuator body.
