Abstract

A thin film, magnetic recording head for very narrow magnetic track widths is described. The head is unique in that the magnetic track width is determined by the dimension of a "V"-shaped hole etched into the deposition substrate, rather than by photolithographic techniques as is conventionally done. The head also requires only a single step for deposition of both magnetic pole layers, a considerable savings where thick magnetic films are needed to achieve adequate magnetic performance.
