Abstract
In this paper, time domain network analysis methods are used to measure the electrical impedance of a magnetic disk drive write head, An incident step capable of delivering ±73 mA to the write coil simulates typical operating levels. The paper compares results to more common vector network analysis measurements, which are done at small-signal levels. It discusses the application of the measured transient response to high data rate recording
