In hydrostatic air bearings for tape guiding it has been common practice to use a compliant guide at one edge of the tape to force the tape against a fixed reference guide on the other tape edge. The inherent asymmetry of this arrangement tends to produce a pressure gradient across the width of the tape. This pressure gradient can be reduced or eliminated by providing a tape guiding path in which the air bearing under the tape is vented at both guide surfaces. The figure shows one arrangement by which this may be accomplished.
