ABSTRACT:
An actuator device of a hard disk drive for reducing a disturbance affecting an actuator. The actuator device has a guide unit connected or attached to an actuator arm for reducing a disturbance affecting the actuator, caused by an air flow generated from a surface of the disk during disk rotation. The guide unit maintains a laminar flow of air between the disk and the actuator arm as the disk is rotated by a spindle of the hard disk drive.
