Compliant tape guides can oscillate and thus fail to guide the magnetic recording media. One way of circumventing this problem is by utilizing damping from selected application of a polymer (Fig. 1). A compliant edge guide or flange 10 is provided to laterally guide a tape 11 across a bearing, such as an air bearing. Lateral vibrations of the compliant guide are damped by the application of a polymer to the outside of fingers 12 of the guide. Another way of controlling compliant guide oscillation is by designing the guide 20 so that the fingers 22,24 have identical spring rates but differing mass distributions (Fig. 2). This redistribution of mass gives different harmonic (vibratory) components to the fingers. A design mix of such fingers breaks up vibrations which would otherwise resonate sympathetically.
