An automatic thermal throttling protection method is described. The system may comprise a perpendicular recording head having a write pole, and a recording medium including a hard magnetic recording layer and a soft magnetic underlayer. At least one sensor is arranged to detect the leading edge of the video pulses after they have passed along the transmission lines. A target rotational speed of the pump is set in accordance with the normal operating range. Also, a method of assembling the aircraft wing. This interconnecting datalink allows additional information to be passed without changing the SS7 protocol or the variety of unique protocols from each of the network components.
