Abstract
The present invention prevents a head/slider assembly fixed on a flexure of a head suspension assembly from having an undesired pitching motion when an unexpected excess shock is applied to a hard disk device when the head suspension is at the best position of the unload ramp. A disk drive device in accordance with the present invention comprises: a rotating data recording disk; a head suspension assembly containing a front portion and a rear portion, with the front portion being provided with a tab; a device coupled to the rear portion of the head suspension assembly to move the front portion between an inner most position and an outer most position along a radial direction of the rotating data recording disk; a ramp element containing a support surface for engaging with the tab of the front portion of the head suspension assembly when the front portion is moved to the outer most position; and a flexure mounted on said front portion of the head suspension assembly, and having a front portion disposed towards the tab of the head suspension assembly and a rear portion disposed towards the rear portion of the head suspension assembly.
