Abstract
A multitrack head assembly has a plurality of magnetic heads arranged side-by-side along a transducing gap line extending across an upwardly facing tape-engaging surface which includes a series of elongated coplanar ribs alternating with low-pressure channels on both sides of and orthogonal to the gap line. For continuous in-contact recording, each rib is aligned with a particular one of the magnetic heads and has a width that is greater than the width of the transducing gap of the head with which it is aligned; furthermore, each rib has a gently curved tape-engaging surface with a radius of curvature R.sub.1 in a direction orthogonal to the gap line and a radius of curvature R.sub.2 in a direction substantially parallel with the gap line, where R.sub.1 and R.sub.2 are not necessarily the same.
