Abstract
A magnetic head having a pair of longitudinal channels in a tape bearing surface that flank each transducer. The channels reduce the effective height of debris in the channels near the transducers. The channel floors may have a transverse slope, and the tape bearing surface between channels may be tapered. Transverse slots help direct debris away from the transducers. The channels overlap the end sections of the transducers and help to define the shape and position of the transducer's active section. 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.
