Abstract
A disk drive unit such as a hard disk drive is provided in which the efficiency of manufacturing processes, cost reductions, and space savings are achieved. The hard disk drive has a stopper that is arranged between a set of coil holding arms of an actuator. The stopper regulates inward and outward turning of the actuator. A magnet is embedded in the stopper and holds a magnetic head of the actuator on a ramp.
