ABSTRACT:
A magnetic tape head assembly is provided for use with a magnetic tape storage medium. The assembly includes an interior tape head module having a magnetic gap with transverse slots on each side of the gap which substantially eliminate air and debris entrained between the module and the tape as the tape moves over the module. The assembly also includes a first exterior tape head module on one side of the interior module, the first exterior module having a magnetic gap with transverse slots on each side of the gap and a width greater than that of the interior module. The assembly still further includes a second exterior tape head module on another side of the interior module, the second exterior module having a magnetic gap with transverse slots on each side of the gap and a width greater than that of the interior module. The distances between the magnetic gaps of the modules are each approximately 0.060 inches. The distances between the magnetic gaps and the outsides of the first and second exterior modules are sufficiently long to accommodate tape wrap angle variations such that the tape adequately engages the exterior modules. The interior and exterior modules each have a cylindrical contour with a radius of approximately 0.390 inches.
