Suspension assembly having flexure limiter and actuator of a hard disk drive using the same

摘要

A suspension assembly having a flexure limiter and an actuator of a hard disk drive using the suspension assembly are provided. The suspension assembly elastically biases a slider toward a surface of a disk, and a read/write head is mounted on the slider. In the suspension assembly, a load beam is coupled to an end portion of a swing arm of the actuator. An end-tab is extended from a front end of the load beam and parks the head on a ramp. A flexure supports the slider and has a rear end fixed to a disk facing surface of the load beam and a front end extended toward a front end of the load beam. A flexure limiter limits a rolling and pitching movement range of the flexure. The flexure limiter is bent from the front end of the flexure toward the end-tab and has a hole through which the end-tab passes. In addition to the pitching and rolling movements of the flexure due to the shock applied to the actuator, the twisted deformation of the flexure can be limited below a predetermined level. <IMAGE>
