Abstract
A magnetic tape head assembly is disclosed for use with a magnetic tape storage medium. The assembly includes an interior tape head module having a magnetic gap with 18 tape head elements, and a first exterior tape head module adjacent to one side of the interior tape head module, the first exterior tape head module having a magnetic gap with 18 tape head elements. The assembly also includes a second exterior tape head module adjacent to the other side of the interior tape head module, the second exterior tape head module having a magnetic gap with 18 tape head elements. The distances between consecutive magnetic gaps of the interior and exterior modules are each approximately 0.150 inches, the interior and exterior modules together define a tape interface contour, and the tape head assembly is capable of writing and reading a high coercivity, high density metal particle tape media, and reading a low density CrO.sub.2 tape media. In the preferred embodiment, the interior module is a write head with 18 write elements, and the exterior modules are each read heads with 18 read elements.
