Abstract

Results of modeling, observations of recorded pit morphology, and measurements of optical disk performance are presented for an overcoated organic dye-binder recording medium. With thin (~50-nm) overcoats on such media, a laser pulse forms a pit in the dye-binder [laser write and read (LWR)] layer, while the overcoat forms into a dome over the pit. Pits have well-defined edges and are surrounded by a shallow rim. Thinly overcoated LWR media demonstrate good laser recording sensitivity (~10(-2)J/cm(2)), high carrier- to-noise ratios (>66 dB), and low raw bit error rates of 10(-5)-10(-6). Also, no debris is generated during the laser recording process.
