Abstract
An E-block of an actuator for use in a data handling system to support a read/write head adjacent a recording surface. The E-block is formed by providing feed stock along a planar orientation, drawing a portion of the feed stock out of plane to form an extension portion, and stamping the feed stock to separate an actuator arm member having a substantially planar actuator arm from which the extension portion extends, the actuator arm configured to support the read/write head. A planar motor support member configured to support a coil of an actuator motor is also stamped from the feed stock. The actuator arm member and the motor support member are stacked and attached using a suitable process such as swaging or welding. The extension portion of the actuator arm member establishes a desired axial separation distance between the motor support member and the actuator arm.
