ABSTRACT:
An actuator for carrying a read/write head into engagement with a surface of a recording medium includes a carriage assembly including a load beam upon which the read/write head is mounted, and a pair of barriers disposed on opposite sides of the load beam to constrain lateral movement of the load beam to prevent damage to the read/write head when the disk drive undergoes shock. Extending from the load beam may be a pair of wings that ride upon ramped surfaces that are, disposed within the disk drive, as the actuator moves to engage and disengage a data storage medium. Preferably, the barriers are disposed outboard of the wings, so that the wings will contact the barriers and thereby restrain movement of the actuator when a mechanical shock is applied to the disk drive. By restraining movement of the actuator, the barriers protect the heads from mechanical shock.
