One of the subassemblies includes a magnetically conductive core with an electrically conductive coil wrapped thereover to enable first and second current flow directions in the circuit. The other of the subassemblies includes a magnetically conductive core and at least one magnet secured thereto. Transmission of an electric current through the electrically conductive coil induces rotation of one of the subassemblies relative to the other of the subassemblies to rotate the recording head about an axis that is perpendicular to recording media on the recording head. The disclosed rotary actuator facilitates quick and accurate recording head position changes due to low inertia of the rotating subassembly as well as reduced inductance and symmetrical mass distribution of the actuator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Rotary actuator with coil winding portions having opposing current flow directions","description":"A rotary actuator for positioning a recording head in a data storage mechanism and that includes first and second cylindrical subassemblies separated by an air gap.
