Abstract
A longitudinal recording head () for use with magnetic recording media includes a non-uniform gap () between first () and second magnetic () poles which focuses magnetic flux onto a small area of the magnetic recording medium. The non-uniform gap is preferably in the form of a cavity that is contoured to produce the desired flux pattern. Longitudinal recording heads incorporating the non-uniform gap are capable of improved recording densities.
