An arbitrary gap thin film magnetic recording head is fabricated by
forming a substrate based on traditional vertical planar thin film head
wafer technology which is designed to produce an integrated subgap and
subpole substrate structure. The recording head includes a pair of
magnetically permeable thin film subpoles, separated by a low
permeability subgap structure. An electrically conductive coil may be
embedded, in part, within the subgap structure. Thus, the subpoles and
subgap structure form part of a magnetic circuit. A highly permeable
magnetic surface film spans from one subpole to the other having one or
more arbitrary gap patterns. That is, a surface thin film is deposited
and patterned on the tape bearing surface of the head to optimize various
element configurations, gap patterns and head-to-tape medium contact.
