A rotating head magnetic tape transport wherein a helical wrap of flexible magnetic tape is formed about a stationary tubular mandrel and a rotatable headwheel which carries a slotted head of generally spherical flying contour. This rotating head includes a generally spherical surface profile to insure that the head flies with close microinch adjacency to a length of magnetic recording tape. The head's spherical profile includes two parallel airflow slots which extend in the direction of head movement. A uniform, stable, hydrodynamic air film is developed over a relatively large area, generally centered on the head's transducing gap.
