ABSTRACT:
Slant gap magnetic heads, comprised of back-to-back wedges, are produced by an inventive procedure: Bars of discrete coil-wound thin-film heads--which bars are, cross-sectionally, L-shaped--are stacked with respect to each other. By dicing through the stack of bars at an angle commensurate with the degree of gap-slant, discrete slant gap head structures are produced. With minimal contouring/lapping, such head structures may be finished for use in recording equipment that records chevron-like alternating skewed information tracks.
