Abstract
A disc drive has an actuator assembly that includes an actuator arm and a suspension having a load beam for supporting a head above a surface of a disc. The actuator assembly includes a plurality of surface features formed on a surface of at least one of the actuator arm and the load beam to reduce aerodynamic drag forces experienced by the actuator assembly. The disc drive may also include an air dam having a finger extending over the surface of the disc, where the finger includes a plurality of surface features to reduce flow separation of an airflow passing over the finger. The surface features may comprise dimples or V-shaped shark skin denticles.
