Abstract:
A method of restraining a head disk assembly (HDA) within a servo track writing apparatus (STW), wherein the HDA comprises: a housing; a spindle shaft coupled to the housing and rotatably supporting a spindle having at least one storage disc; and a pivot shaft coupled to the housing, the pivot shaft pivotally supporting an actuator assembly for moving a transducer head relative to the at least one disc, the method comprising steps of:(a) placing the HDA into the STW, the STW having opposing clamp members with opposing contact points; (b) clamping the HDA between the clamp members such that the contact points operatively engage each end of both the pivot shaft and spindle shaft; and (c) applying a compressive load to the HDA, wherein the opposing contact points load against the ends of the pivot shaft and the spindle shaft to restrain non-rotational movement of the actuator assembly and spindle.
