Abstract

A very fast calculation method of calculating the three-dimensional read head field from a perpendicular recording medium is presented using a head characteristic matrix K, and the medium charge with a spacing loss correction. The numerical integration in the evaluation of the matrix can be replaced with an infinite sum, speeding up the calculation significantly. The head characteristic matrix has a physical significance as the inverse matrix of the self-magnetostatic energy with a charge placed on the air bearing surface (ABS) of the read gap.
