Abstract:
A disk drive including an actuator arm assembly and an arm mounting device on which said arm assembly is pivotally mounted for movement about a pivot axis,said arm assembly having at least one rocker member with a first abutment,said mounting device comprising a pillar member extending along said pivot axis and having a second abutment,said first and second abutments forming a pair of abutments at least one of which is curved,said arm assembly being mounted on said mounting device with said first abutment abutting said second abutment along said pivot axis and in rolling engagement with said second abutment,and said disk drive further comprising a resilient bias device that has a first arm in contact with the radiused surface of the mounting device and a second arm in contact with the radiused surface of the actuator arm assembly acting to form a clasp which exerts force to urge said first abutment into contact with said second abutment, and a flexible restraining member secured both to said mounting device and to said arm assembly to prevent movement of said rocker member in a direction perpendicular to said pivot axis while permitting pivotal movement of said actuator arm assembly about said pivot axis, at least one of said abutments being mounted on a movable mounting to prevent sliding movement between said first and second abutments during flexing of said restraining member.
