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/cm2), 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.
