Abstract

A cusp-field single-pole-type (CF-SPT) head that has a main pole with double-sided tapers and generates a large field (>20 kOe) is described. An FEM simulation of the head with a discrete-track media has been carried out to analyze high track density recording. DC stray field for various combinations of recording layer and non-magnetic layer widths are derived. It is found that the recording field at the track center becomes larger as the magnetic layer width gets smaller; however, the stray field to the adjacent tracks cannot be reduced by introducing the discrete-track media.
