OPTICAL DATA RECORDING MEDIA

摘要

An optical data recording medium (100) includes a substrate (220), and a dye coating (230) established on the substrate (220). The dye coating (230) including an absorber (239) having a light absorption maxima at a first waveband, and a contrast agent (240) having a light absorption maxima at a second waveband that is at least 100 nm apart from the first waveband. The medium (100) is configured to exhibit a reflectivity greater than or equal to 45% and a push pull signal (PPa) at the second waveband equal to or less than 0.4.
