A multi-layer imaging medium has a layer that absorbs radiation at a wavelength used by an optical auto-focus system. Spurious reflections are suppressed. The layer transmits radiation at a wavelength used to image the medium. The layer may function as a support layer for the medium. Thermal imaging media may be made according to the invention.
