Abstract
Considering the works of (a) Satoh, Ohtsubo and Shimada and (b) Wilton, Map ps and Shute, the magnetic fields due to variable potential distributions o ver the surfaces of curvilinear single-pole heads with an underlayer are ex amined using a generalised Schwarz-Christoffel conformal mapping method. Th ree particular head shapes are considered, including the conventional recta ngular head model for comparison. It is found for some systems, as in the r ectangular cases of Wilton, Mapps and Shute, whose works we use as a model, that there is improvement in the peak field strength with respect to the c orresponding constant potential head. A method to determine the curve in th e complex-potential plane and its corresponding mapping formula for a gener al system using the same generalised Schwarz-Christoffel method is proposed .
