Abstract :
Analytical models of ideal infinitesimally thin probe-type heads have been presented and compared with a model of an ideal ring-type head. It is shown that with respect to readback resolution the characteristics of probe models are inferior to those of the ring model. It is also shown that resolution of the probe model is reduced further if media with a soft magnetic underlayer is used.
