An endcap for use on an actuator arm carrying a single head gimbal assembly, the endcap comprising a body, and a shielding feature extending from the body for reducing windage excitation of the head gimbal assembly. A method for operating the output control signal generating circuit causes a clock signal to be delayed by a selectable number of additional clock cycles, thereby insuring the outputting of a data signal only at a time when the data is valid. The donor base station node configures a subframe configuration pattern. Next, a second oxide layer is deposited on top of the first conductive layer and the first oxide layer. In another preferred embodiment the treadmill is sized to support a cycle.
