Abstract: A unique system and method for ordering commands may reduce disc access latency while giving preference to pending commands. The method and system involves giving preference to pending commands in a set of priority queues. The method and system involve identifying a pending command and processing other non-pending commands in route to the pending command if performance will not be penalized in doing so. The method and system include a list of command node references referring to a list of sorted command nodes that are to be scheduled for processing.

Abstract: An apparatus is described which reduces flow-induced disturbances of the head. A disc drive assembly is provided which includes a basedeck and top cover. A spindle motor mounted to the basedeck which rotates around a central axis; at least one magnetic storage disc mounted to the spindle motor for rotation around the central axis and an actuator arm assembly. The actuator arm assembly includes an actuator arm rotatably attached to a pivot axis and a suspension arm attached to a distal end of the actuator arm. A magnetic transducing head is attached to the suspension. The head is used to read and write data to the magnetic storage disc. Finally, a leading surface portion of the actuator arm utilizes several turbulence-reducing portions laterally recessed so as to guide an airflow to reduce a flow-induced disturbance acting on the transducing head.
