Abstract
A method and system for overcoming force which inhibits movement of a data storage device are provided. The invention includes generating momentum in a moveable member and then utilizing the momentum of the moveable member to generate a large impulse force on a stationary body (e.g., the data storage device) to overcome the movement-inhibiting force thereon. This is accomplished by allowing the moveable member to move along a trajectory independently of the stationary body, thereby building momentum in the moveable member. The subsequent impact of the member on the body overcomes the force. The moveable member can then also be used, in one embodiment, to continue driving the body during system operation.
