Abstract
A magnetic tape is guided past a transverse-scan rotating transducing head drum which is shaped to create an air bearing film between the drum and tape, so that only the tips of the heads themselves engage the tape. To avoid adverse influence on the air bearing, the guide means is arranged to engage the tape only at points remote from the plane of the head drum, and to induce at these points a transverse curvature in the tape that is of smaller radius than that of the head drum, ensuring that the tape rests closely on the air bearing across the entire tape width.
