The optical recording characteristics of Drexon® optical memory disks have been evaluated at two krypton ion laser wavelengths, 647 nm and 799 nm. Reflectivity modulation and carrier-to-noise ratios were obtained at each wavelength for several input parameters. These parameters included optical reflectivity of the media, incident laser power, media velocity, and recording pulse frequency. Optical and electron microscopy were used to evaluate the appearance of the recorded pits. Measurement results are presented.
