Abstract: A magnetic head (10) having a pair of longitudinal channels (30, 32, 230, 232) in a tape bearing surface (18) that flank each transducer (24). The channels reduce the effective height of debris in the channels near the transducers. The channel floors (258, 260) may have a transverse slope, and the tape bearing surface between channels may be tapered. Transverse slots (254, 256) help direct debris away from the transducers. The channels overlap the end sections (34, 36) of the transducers and help to define the shape and position of the transducer's active section (37). When applied to a two pole write transducers, the channels narrow and equalize the effective width of the top and bottom poles. Narrow equal-sized poles can write narrow data tracks with a track width that is independent of the magnetic medium's direction of motion.

Abstract: A magnetic tape head assembly (10) for use with a magnetic tape medium. The assembly includes an interior tape head module (14) having a magnetic gap (18) with 16 or more tape head elements, and a first exterior tape head module (12) adjacent one side of the interior module. The first exterior module has a magnetic gap with 16 or more tape head elements. The assembly also includes a second exterior tape head module (16) adjacent the other side of the interior module. The second exterior module has a magnetic gap with 16 or more recording elements. The distances between consecutive magnetic gaps of the interior and exterior modules are each approximately 60 microns, and the interior and exterior modules together define a semi-circular tape interface contour. In the preferred embodiment, the interior module is a write head with 16 write elements, and the exterior modules are each read heads with 16 data read elements and 6 servo read elements.
