Various approximation schemes in head field calculations for conventional ring heads and thin film heads for longitudinal recording and pole keeper heads for vertical recording and, to a lesser extent, the readout waveform of the magnetoresistive heads are broadly discussed. Relative merits, demerits and the precision of each calculation method are also briefly discussed.
