Abstract

A two bump magnetic head for writing and reading information to a tape includes a merged-pole read/write element structure with inverted write elements. Each inverted write element includes top and bottom write poles. The write poles are fabricated such that the longitudinal dimension of the bottom write pole is smaller than the longitudinal dimension of the top write pole in a zero throat region. This results in an “inverted” structure. An upper portion of the bottom write pole is milled in at least the zero throat region early in fabrication to produce a precise width adjoining a write gap. The trimmed upper portion of bottom write pole results in an improved write geometry that produces tightly defined tracks.
