A rotary actuator motor is provided including a stationary coil section and a rotating magnet. The magnet is incorporated with the pivot bearing assembly, and the coil section is aligned with the magnet along an axis of rotation of the actuator. The magnet fully encircles the axis of rotation. The coil comprises one or more closed loops of electrically conductive material. The motor in this arrangement maintains a much smaller profile in comparison to a traditional voice coil motor that is mounted to a yoke extending away from the axis of rotation of the actuator.

An actuator assembly is provided having a ramp for unloading a transducing head from a storage medium. The actuator assembly includes an actuator arm rotatable about a pivot point and configured to access data on a storage medium. The actuator arm has a base end coupled to a lift tab and a distal end coupled to a transducing head. The actuator assembly also includes an inclined surface located adjacent the base end. The inclined surface is configured to engage with the lift tab to guide the transducing head away from the storage medium.
