Abstract:
A head stack assembly for use in a disk drive, the head stack assembly comprising:a body portion having a bore, the bore defining a pivot axis; at least one actuator arm body extending from the body portion and defining a longitudinal axis, the at least one actuator arm body being sized and configured to rotate about the pivot axis disposed perpendicular to the longitudinal axis; at least one load beam extending from the at least one actuator arm body along the longitudinal axis; a head connected to the at least one load beam; a linear actuator connected to the body portion, the linear actuator being sized and configured to selectively expand and contract; and at least one actuation linkage connected with and interposed between the at least one actuator arm body and the at least one load beam, the at least one actuation linkage being further connected to the linear actuator, the at least one actuator linkage extending longitudinally along the actuator arm body; and wherein selective expansion/contraction of the linear actuator moves the at least one actuation linkage which moves the connected at least one load beam and the connected head with a transverse component relative to the longitudinal axis of the associated at least one actuator arm body.
